16 Introduction The Waters Reagent Manager is a high-performance pump designed for use as a dependable metering pump for general laboratory or industrial use. As a single-piston, pulse-dampened pumping system for post-column reagent delivery, the Waters Reagent Manager combines the most important aspects of solvent delivery: High precision and accuracy Reliability Smooth solvent flow Ease of use The reagent manager is designed for optimum performance, operational convenience, and safety. The following figure shows the front view of a Waters Reagent Manager. Waters Reagent Manager Front control panel Mode Fault Run ml/min PSI Hi Pr Lo Pr PRIME/PURGE Pump head with seal wash Prime Run/ Stop FILTER/OUTLET Waters Reagent Manager Power switch I/O TP Overview

17 Features The reagent manager includes a full array of important features, such as pulse damping, a nonmetallic flow path, automatic washing of the pump piston seal, and an easy-to-use front control panel. Other features include a convenient priming/purging system, a high-pressure inline filter, spill protection, and a remote start/stop feature. The Waters Reagent Manager operates from 0.05 to 2.00 ml/min up to 2500 psi. The flow rate can be set in 0.01-mL increments with a precision of 0.5%. The pump automatically shuts down at user-settable high- or low-pressure limits. The pump contains a pulse damper to minimize detector baseline noise. Low flow modulation of the reciprocating, single-piston pump is achieved with an advanced electronic rapid-refill design, programmed stepper motor acceleration, and a pulse damper. The rapid refill design reduces pulsations in the pump cycle and provides constant, stable flow from the pump at high pressure. Polymeric flow path The materials that make up the fluidic pathway of the Waters Reagent Manager are nonmetallic and biocompatible. They include: polyetheretherketone (PEEK) polytetrafluoroethylene (PTFE) Tefzel sapphire ruby polyethylene fluoroethylene propylene copolymer (FEP) ultra-high molecular weight polyethylene (UHMWPE) Wetted surfaces in the pump head include ruby, sapphire, and polymer (PEEK). Features 1-3

18 Automatic seal wash During pump operation, the pump head is continuously washed in the region behind the primary high pressure seal. The seal washing action helps to reduce seal wear by washing away the microscopic layer of solvent that wets the area between the piston and the seal. If you use buffered solvents, the solvent layer can evaporate behind the seal and deposit crystals on the piston. Crystals on the piston can abrade the pump seal and cause premature seal failure, leakage, and damage to the pump. The seal-washing pump head washes away the film of solvent before crystals can precipitate. Front control panel A keypad and LED display on the front panel allow you to quickly enter parameters before and during a run. The solvent-resistant membrane keypad has touch keys, while the display provides status and monitoring information for the pump: The four-digit LED front panel display shows the flow rate or pressure. The status LED indicators show the operational status of the pump. Priming and purging Filters The prime/purge valve and the Prime key on the front panel provide quick and easy solvent introduction and rapid solvent changeover using the priming and purging feature. To help maintain the solvent quality through the pump flow path, the reagent manager uses the following filters: An inlet filter In the solvent reservoir (external, slip-on type) A high-pressure inline filter Between the pulse damper and the restrictor coil An outlet filter At the filter/outlet port 1-4 Overview

19 Spill protection The reagent manager has internal spill protection in case of leaks in the flow path. In the event of a leak, solvent drips to the drip pan and is routed to the waste fluid drain connector on the bottom right side of the pump. Recommendation: Provide a solvent bottle tray for the top of the pump if you decide to place solvents or any instrument with fluidic lines on top of the pump. For example, a solvent bottle tray can provide storage for solvent reservoirs and a seal wash reservoir, with leak protection for a spill. Remote Start/Stop feature You can easily integrate the reagent manager into your HPLC system using remote stop/start inputs and stop output capabilities. To accomplish this, the reagent manager accepts remote run/stop input (contact closure) signals from other instruments. It also generates a remote stop output signal to an instrument when a high- or low-pressure fault is triggered. This capability requires a remote start/stop cable, which is included in the startup kit. Fluid-handling components The fluid-handling components of the Waters Reagent Manager are shown in the following figure. Fluid-handling components 1-5

20 Pump fluid-handling components Pump outlet Pump head Seal wash outlet Seal wash inlet Pump inlet Prime/purge valve Filter/outlet valve TP01563 Caution: To prevent solvent leaks from the pump outlet, position the solvent reservoir below the pump inlet before you connect the pump outlet fitting. The following table describes the functions of the major fluidics components. Fluid-handling components Component Pump head Pump inlet and outlet Function Draws in and delivers solvent. Maintains flow direction of solvent through the pump using check valves that open in one direction only. 1-6 Overview

21 Fluid-handling components (Continued) Component Prime/purge valve Filter/outlet valve Seal wash inlet and outlet Function When the valve is open, allows priming and purging of the pump. Considerations: Connecting a syringe to the valve allows you to draw solvent through the pump for priming. Operating the pump allows solvent to flow through the pump and out the valve for purging. When the valve is closed, high-pressure flow is directed to the filter/outlet valve. Routes solvent out of the pump to a fitting, injector, column, or detector. Washes the piston seal with seal wash solvent using check valves to maintain flow of seal wash in one direction. Flow paths The flow path of a solvent through the pump is as follows: During priming and purging Solvent flows from the solvent reservoir through the pump head to the pulse damper and out the prime/purge valve. The flow rate ramps up to 10 ml/min during priming and purging. During normal operation Solvent flows from the inlet filter in the solvent reservoir through the pump head to the pulse damper, prime/purge valve, inline filter, restrictor coil, and out the filter/outlet. Tip: As shown in the following figure, the seal wash solvent (dotted lines) continuously flushes the pump in the area behind the piston seal. Fluid-handling components 1-7

22 Flow paths of solvents through pump Reagent manager Pulse damper Pump Head Seal wash reservoir Outlet check valve for seal wash Solvent outlet check valve Prime/purge valve High-pressure inline filter Fluid waste Solvent reservoir with filter Inlet check valve for seal wash Solvent inlet check valve Restrictor coil Filter/outlet Next device Pump cycle The pump cycle consists of two phases, the delivery phase and the refill phase. During the delivery phase, the pump piston moves forward at a constant linear speed, and is eccentrically driven by the motor. This results in a constant, stable flow from the pump at high pressure. During the refill phase, the piston quickly retracts, refilling the pump head with solvent. Although the pump head output flow completely stops during refill, the pulse damper transiently maintains some flow. In addition, the motor speed is adjusted by the microprocessor to facilitate an efficient refill phase. The combination of increased motor speed and the rapid refill design of the cam generates a refill time of less than 5% of the pump cycle at 1 ml/min. 1-8 Overview

23 Pulse damper The patented diaphragm pulse damper helps to maintain the flow rate and pressure. The pulse damper consists of a compressible fluid (isopropanol) held in an isolated cavity by a flexible diaphragm. During the delivery phase, the pressure of the solvent displaces the diaphragm, compressing the fluid in the cavity and storing energy. During the refill phase, the pressure of the pumped solvent on the diaphragm is reduced and the compressed fluid expands, releasing its stored energy and continuing to pressurize the solvent path. Because the amount of solvent in contact with the pulse damper is small (0.9 ml at 2500 psi), and the flow past the damper is completely swept, solvent changeover is rapid. The pulse damper requires a back pressure of approximately 500 psi or greater. A length of small-bore, restrictor tubing (the restrictor coil) between the pulse damper and the filter/outlet ensures that this minimum back pressure is maintained. Fluid-handling components 1-9

26 Remote Start/Stop feature When the reagent manager is configured for remote start/stop operation, the external control device triggers the pump on or off by contact closure signals sent over a cable. If a fault occurs in the pump during operation, the reagent manager stops running and sends a signal to the external device. The reagent manager startup kit contains the remote start/stop cable for remote start/stop operation. See Connecting for remote start/stop operation on page 2-5, for instructions on how to install the remote start/stop cable Overview

During pump operation, position the bottom of the reservoir about 4 inches (10 cm) higher than the pump head. If you use high-viscosity solvents, you may need to elevate the reservoirs as much as 18 to 24 inches (46 to 61 cm) above the inlet to prevent bubble formation as the pressure drops during the refill phase. Making fluidic connections 2-15

42 To connect the solvent reservoir to the pump solvent inlet 1. Measure the length of inlet tubing required to connect the solvent reservoir to the pump inlet. The inlet tubing should be as short as practical to minimize pressure losses on the inlet side of the pump during the refill phase (to prevent bubble formation). 2. Use the tubing cutter to cut the PEEK tubing to the measured length. Make sure the cut end is straight and free from burrs. 3. Slide a nut and then a ferrule over one end of the tubing, as shown in the following figure. Attaching a ferrule and nut to tubing Nut Tubing Ferrule Tubing End (straight and smooth) Caution: To avoid damaging the ferrule, do not overtighten the nut. 4. Firmly seat the tubing end into the inlet on the pump, then finger-tighten the nut. 5. Insert the free end of the inlet tubing through the cap of the solvent reservoir. 6. Cut a 1.5-inch (3.8-cm) section of outlet tubing and slide half of its length over the end of the inlet tubing. 7. Insert the tubing fitting of the inlet filter into the outlet tubing sleeve at the free end of the inlet tubing. 8. Install the cap onto the solvent reservoir (containing filtered, degassed solvent) and push the outlet tubing through the cap until the filter reaches the bottom of the reservoir Installation

43 Connecting the pump outlet to a device To connect the pump outlet to a device 1. Measure the length of outlet tubing required to connect the pump outlet to a device. Use a polymeric tubing cutter to cut the tubing to the measured length. Ensure that the tubing is cut squarely with no burrs or crimps and that the center hole is open. 2. Remove the fitting plug from the pump filter/outlet fitting. 3. Slide an outlet nut and then a ferrule over one end of the tubing (see the above figure). 4. Firmly seat the tubing into the filter/outlet fitting, then finger-tighten the nut. 5. Unscrew the assembled fitting and verify that the length of tubing extending beyond the ferrule is 0.12 inch (3 mm). 6. Finger-tighten the nut again. 7. Repeat steps 3 through 6 for the other end of the tubing only after you have primed the pump and flushed the system, as described in Priming the pump on page 3-6. Installing and priming the seal wash tubing The pump head seal wash requires 250 ml to 500 ml of seal wash solvent. The seal wash solvent drains to a fluid waste container below the pump. Use an aqueous seal wash solvent with enough organic content to inhibit bacterial growth. To install the seal wash tubing 1. Cut the seal wash tubing at its midpoint. 2. Install seal wash fittings on one end of each length of seal wash tubing. 3. Screw the fitting on one length of tubing to the seal wash inlet as shown in the following figure. Ensure that the fitting and tubing fit tightly to prevent leaks. Making fluidic connections 2-17

44 Connecting the seal wash tubing Tubing from seal wash outlet to waste container Tubing from seal wash reservoir to seal wash inlet TP Install the other end of the tubing in the seal wash reservoir. Secure the tubing in the reservoir to ensure that the tubing stays immersed during pump operation. Position the reservoir at least 4 in. (10 cm) higher than the pump head. 5. Screw the fitting on the other length of tubing to the seal wash outlet. Ensure that the fitting and tubing fit tightly. 6. To prime the seal wash tubing, connect the seal wash fitting to the priming syringe, then connect the syringe to the free end of the seal wash outlet tubing. 7. Draw 10 ml to 20 ml of seal wash solvent through the seal wash outlet. Ensure that the tubing is filled with solvent and that no bubbles remain in the lines. 8. Disconnect the syringe, then install the end of the seal wash outlet tubing in a waste container located at a level below the pump so that fluid drains by gravity. Secure the tubing to ensure that the tubing stays in the container during pump operation Installation

51 Preparing the Reagent Manager The procedure to prepare the Reagent Manager for operation depends on the status of the pump. If the pump is dry, you must prime the pump (see Priming the pump on page 3-6). If you are changing solvent, restarting the pump after a long idle time, or adding fresh solvent, and the pump contains fluid, you must purge the pump (see Purging the pump on page 3-7). Solvent guidelines Required Materials Priming syringe Solvents for the system, filtered and degassed Waste tubing Waste container Seal wash solvent Selection and preparation of solvents to use in the Waters Reagent Manager are critical factors for successful operation. See Appendix D for detailed solvent consideration information. Caution: Do not use any of the following solvents in the Waters Reagent Manager because they damage PEEK components. Methylene chloride Tetrahydrofuran (THF) at greater than 10% (v/v) Freon Concentrated sulfuric acid (H 2 SO 4 ) Concentrated nitric acid (HNO 3 ) Preparing the Reagent Manager 3-5

52 Also keep in mind the following solvent guidelines: Use methanol to prime a new pump or a pump that has been stored for an extended period. Use an intermediate solvent when you change between solvents that are not miscible. Always keep the solvent level in the reservoir at least 4 inches (10 cm) higher than the pump inlet. Do not place solvent reservoirs on top of the Reagent Manager. Use only filtered, degassed solvents. After using a buffer, purge the pump with HPLC-grade, distilled, or deionized water to prevent crystallization and damage to the piston or seal. Know the properties of the solvents under different pressures. Dedicate a solvent supply tube and filter assembly for each solvent. If this is not possible, purge the tube and filter of any remaining solvent before you use a new solvent. To prevent cross-contamination of solvents, dedicate a set of glassware for preparing, storing, and supplying each solvent. Once a container has been used for a solvent, do not use it for any other solvent unless it has been thoroughly cleaned. Warning: To avoid chemical hazards and prevent injury, always observe Good Laboratory Practices when you handle solvents. Know the physical and chemical properties of the solvents you use. See the Material Safety Data Sheets for the solvents in use. For more information on solvent properties, see Appendix D. Priming the pump To prime the pump 1. Power on the pump. 2. Raise the reservoir so that its base is above the level of the pump inlet. 3. Open the prime/purge valve by turning it fully counterclockwise. 4. Connect the fully discharged priming syringe to the prime/purge valve (see the following figure). 3-6 Operating the Waters Reagent Manager

53 Priming the Reagent Manager Prime/Purge Valve Priming Syringe 5. Press Prime to run the pump. The pump automatically ramps up to 10 ml/min. 6. Draw at least 20 ml of solvent (and any air bubbles) through the pump and into the syringe. 7. Press Run/Stop or any key to stop priming. 8. Close the prime/purge valve by turning it fully clockwise, and remove the syringe. Dispose of solvent properly. 9. Connect the free end of the outlet tubing to the inlet fitting of the next device in your HPLC system and finger-tighten the nut. Purging the pump Purging ensures that all solvent in the fluidic path is replaced with fresh solvent. Caution: When you change between two solvents that are not totally miscible, follow the purging procedure described below, first using an intermediate solvent, then the final solvent. See Appendix D for more information. Before you press the Prime key, be sure the prime/purge valve is open. To prevent damage to the pump, always draw fluid from the prime/purge valve. Do not inject fluid into the prime/purge valve with a syringe. To prevent solvent flow through the pump head under gravity pressure, never leave the pump unattended with the prime/purge valve in the open position. Preparing the Reagent Manager 3-7

54 To purge the pump 1. Perform steps 1 through 9 in Priming the pump on page Press Run/Stop to start the pump. 3. Let the pump run for about one minute to verify that the pump pressure is normal for the selected solvent and flow rate. If the pump pressure is not correct, repeat steps 1 and 2, as necessary. 4. Press Run/Stop to stop the pump. Priming the seal wash tubing If you see air bubbles in the seal wash tubing, prime the seal wash tubing as described in Installing and priming the seal wash tubing on page Operating as a stand-alone pump You operate the Reagent Manager as a stand-alone pump using only the operation keys on the front control panel. Before operating Before you operate the Reagent Manager, ensure that: You have already completed any required priming and purging, as described in Preparing the Reagent Manager on page 3-5. Solvent reservoirs are filled with filtered, degassed solvent. Caution: To avoid chemical hazards and prevent injury, always observe Good Laboratory Practices when you handle solvents. See the Material Safety Data Sheets for the solvents you use. For more information on solvent properties, see Appendix D. Operating the pump The operation keys provide access to all pump operating parameters. Use the Mode, Up, Down, and Run/Stop operation keys to navigate through the parameters.
