7 Overview of the 1 Overview of the Purpose The Mariner (Figure 1-1) is an optional electrospray ionization (ESI) spray chamber and associated parts that allow operation on the Mariner Biospectrometry Workstation at higher flow rates than the standard spray chamber (up to 1.0 ml/min). TurboIon Spray module PB Figure 1-1 Mariner Workstation with Installed Probe function The TurboIonSpray module includes an IonSpray probe that delivers sample and solvent, and a heated Turbo probe that directs a jet of heated gas at the sample stream. The heated gas increases the rate of droplet evaporation, aids desolvation, and increases ion signal. Mariner Biospectrometry Workstation TIS Module Supplement TIS-1

8 Section 1 Overview of the Parts of the TurboIonSpray module Auxiliary gas flow meter The TurboIonSpray module is a modified version of the Applied Biosystems TurboIonSpray Source. It has been physically adapted to fit onto the Mariner Biospectrometry Workstation. Basic operation and performance is unchanged. The TurboIonSpray module includes: TurboIonSpray spray chamber Exhaust trap line and bottle IonSpray probe Heated Turbo probe Exhaust trap line to bottle (bottle not shown) PB Compressed air inlet Figure 1-2 Parts of the TurboIonSpray Chamber TIS-2 Applied Biosystems

9 Overview of the Features The TurboIonSpray source provides the following features: Increased ionization efficiency leading to improved sensitivity at higher flow rates than conventional electrospray, particularly for compounds with extremely high polarity and low surface activity. Accommodates flow rates from 10 µl/min to 1.0 ml/min, with optimum performance at approximately 200 µl/min. NOTE: Below 50 µl/min, you may see decreased sensitivity. Use the standard electrospray spray chamber for applications that require low flow rates and optimum sensitivity. Is mild enough to be used with labile compounds such as peptides, proteins, and thermally-labile pharmaceuticals. Vaporizes 100 percent aqueous to 100 percent organic solvents. Designed to handle common LC and high-throughput flow rates (>200 µl/min, and up to 1 ml/min) without flow splitting. Stable performance for a variety of LC conditions and solvent buffers.

14 Section 2 Installing the 2.2 Installing the TurboIonSpray Spray Chamber Before you begin Adjusting spray tip distance from nozzle Installing the spray chamber Before installing the TurboIonSpray chamber, make sure that either an integrated syringe pump or the front and side panels are installed on the workstation. Do not install the TurboIonSpray chamber if there is no support below the spray chamber platform. If unsupported, the spray chamber may not properly seal at the nozzle area, and can cause liquid or gas leaks. To adjust the distance of the spray tip from the nozzle opening, use the positioning knob and gauge located on the back of the IonSpray probe. The spray tip lateral positioning knob and gauge are difficult to see when the spray chamber is installed on the system. You can adjust before installing the spray chamber, if desired. For instructions, see Adjusting spray tip distance from nozzle opening on page 23. To install the TurboIonSpray spray chamber: 1. Read Spray chamber precautions on page 7 before proceeding. 2. Make sure the spray chamber lever is pulled out (see Figure 2-14 on page 27). 3. Hold the TurboIonSpray spray chamber with two hands, one under the base, one on the Turbo probe (Figure 2-2). The Turbo probe is the front probe when you are looking at the spray chamber with the probes pointing to the right. NOTE: Do not hold the chamber by the IonSpray probe (the back probe). Doing so can change probe position. TIS-8 Applied Biosystems

17 Installing the 2.3 Installing the Exhaust Trap Line and Bottle WARNING Make certain there is no restriction in the tubing between the TurboIonSpray spray chamber vent outlet and the exhaust bottle. If there is any restriction in the tubing, liquid can back up into the spray chamber and pose an explosion hazard. To install the exhaust trap line and bottle: 1. Connect the two lengths of 1/2-inch OD plastic tubing to the connectors on the exhaust trap bottle cap and screw the cap onto the bottle. 2. To one length of 1/2-inch OD tubing, connect the adapter, then connect the exhaust trap inlet tubing (1/4-inch OD plastic tubing with metal connector) to the adapter. 3. Check the length of the combined tubing. It should be just long enough to reach between the spray chamber and the exhaust trap bottle cap, without any extra tubing that might kink and cause a restriction in the line. If it is longer than necessary, shorten the 1/2-inch OD tubing. 4. Remove the end cap from the compressed air fitting on the TurboIonSpray module. Save the end cap. You can replace it on the fitting when the spray chamber is not in use. 5. Connect the exhaust trap inlet tubing (short tubing with metal connector) to the spray chamber by slipping the connector onto the fitting until it locks in place (Figure 2-3).

19 Installing the 2.4 Connecting, Configuring, and Adjusting Nebulizer, Auxiliary, and Curtain Gases In this section Gas functions This section includes: Connecting the gases Configuring the gases Adjusting the gases Gases perform the following functions: Nebulizer gas Breaks solvent into droplets. Auxiliary gas Delivers gas to the Turbo probe. This gas blows directly at the spray to aid desolvation, especially at higher flow rates where the gas can also be heated. Curtain gas Prevents large solvent droplets and uncharged particles from entering into the nozzle. Also aids desolvation. Gas requirements Use one of the following for nebulizer, curtain, and auxiliary gases: Compressed dry nitrogen, grade 4.8 or better Liquid nitrogen in a dewar (requires drying if you see water clusters or water adducts on proteins) Using one gas supply If you want to use one gas supply for all gases, you can connect one line from the regulated nitrogen supply and install a quick-connect tee (provided in the Mariner Workstation startup kit) just before the Gas 1 and Gas 2 connections on the right side panel of the workstation. Mariner Biospectrometry Workstation TIS Module Supplement TIS-13

20 Section 2 Installing the Connecting the Gases Connecting the compressed gas supply To connect the compressed gas supply lines: 1. Using Teflon tubing (1/16-inch ID, 1/8-inch OD), connect the gas sources to the right side of the mass spectrometer (see Figure 2-1 of the Mariner Biospectrometry Workstation User s Guide): Gas Connector Nebulizer 1 Auxiliary 2 Curtain 2 Push the tubing on to the push-on fittings on the mass spectrometer. 2. Regulate the gases at the source between 80 and 100 psi. CAUTION Do not regulate gas above 100 psi. Doing so can damage the gas seals in the Mariner Workstation. Regulating the gas below 80 psi may not generate high enough gas pressure at the flow meters. TIS-14 Applied Biosystems

21 Installing the Internal gas connections on the spray chamber Internal gas tubing between the spray chamber base and the probes may be disconnected when the spray chamber is provided to you. If this tubing is disconnected, connect the internal gas tubing to the probes (Figure 2-4): Nebulizer Connect from the left fitting on the base to the fitting at the base of the IonSpray probe Auxiliary Connect from the right fitting on the base to the fitting at the base of the Turbo probe Turbo probe IonSpray probe PB Auxiliary gas Nebulizer gas Figure 2-4 Connecting the Internal Gas Tubing Mariner Biospectrometry Workstation TIS Module Supplement TIS-15

48 Section 4 Maintenance Installing new PEEK tubing 7. Loosen the PEEK compression fitting at the LC inlet to the probe (Figure 4-7). Do not remove the fitting. 8. Pull the other end of the PEEK tubing (at the tip-end of the probe) out of the assembly and discard. To install new PEEK tubing: 1. Insert the a 20-inch length of inch ID red PEEK tubing into the spray tip end of the probe until it extends out of the other end of the probe. NOTE: To reduce dead volume at flow rates below 200 µl/min, you can use smaller diameter PEEK tubing. However, smaller diameter tubing may plug more easily. 2. Slip a compression fitting over the LC inlet end of the PEEK tubing, with the threads of the fitting toward the end of the tubing. 3. Slip a tapered ferrule on the tubing, with the taper toward the end of the tubing. 4. Insert the tubing, ferrule, and fitting into the LC inlet (see Figure 4-7 on page 41) and bottom the tubing. Tighten the fitting with a wrench to secure the tubing in place. Do not overtighten. NOTE: The LC inlet block provides a grounded liquid junction connection. Do not bypass the LC inlet block. 5. Slip a tapered ferrule over the other end of the tubing (tubing extending from tip end of probe), with the taper toward the end of the tubing. 6. Hold the union over the tip end of the tubing. Push on the PEEK tubing at the LC inlet to bottom the tubing and ferrule in the union. 7. Tighten the union with a wrench to secure the tubing in place. Do not overtighten. TIS-42 Applied Biosystems

49 Maintenance Reassembling 8. When the union is tightened, gently pull back on the PEEK tubing at the LC inlet, then finger-tighten the PEEK compression fitting at the LC inlet to the probe. 9. Check the alignment of the IonSpray probe. Adjust if needed as described in Aligning spray tip and Turbo probe on page 39. Reassemble the base and the spray chamber. Reconnect the nebulizer gas to the Turbo probe and the auxiliary gas to the IonSpray probe. Replace the spray chamber as described in Section 2.2, Installing the TurboIonSpray Spray Chamber. 4.3 Replacing the Lamp Bulb Replacing the bulb To replace the lamp bulb: 1. Remove the spray chamber from the base as described in Removing the spray chamber from the base on page Snap the bulb out of the holder and replace with a new bulb. 3. Reassemble the base and the spray chamber. 4. Replace the spray chamber as described in Section 2.2, Installing the TurboIonSpray Spray Chamber.
