2 Quick TM Flow ters The ASI Quick Flow ter is very elegant in its simplicity. ratios are created by two or more fluid resistors that form a parallel flow path. Quick Flow ters are available with a fixed or adjustable split ratio. Interchangeable fluid resistors make it easy to change split ratios uickly, eliminating tedious adjustments to capillary tubing. The technology can be applied to all applications where a controlled, reproducible split ratio is reuired including LC/MS, flow fractionation, pre/post-column flow splitting mass directed fraction collection, and capillary chromatography. ASI Quick Flow ters come in flow rate ranges which make them compatible with micro, analytical, semi-preparative and preparative inlet flows.

4 Quick TM Fixed Flow ter Unlike conventional splitters that use long lengths of capillary tubing, the ASI Quick Fixed Flow ter uses two compact fluid resistor elements which are designed as cartridges for easy replacement. ASI fluid resistors are analogous to resistors used in an electrical circuit. Resistance values (L) are rated in PSI/mL/min. Because of the extremely low internal volume of the fluid resistors, the solvent composition in both resistors at any instant in time is the same, and therefore viscosity changes associated with gradient runs do not impact the split ratio. Quick Fixed Flow ters provide a fixed split ratio with extremely low dead volume. Delay volume on the low flow rate side is as low as 100 nanoliters depending upon the resistor cartridge selected. The split ratio is not affected by changes in solvent viscosity or pressure, and is extremely stable and reproducible. The interchangeable fluid resistors are available in a wide range of values which make it possible to create split ratios from 1:1 to as high as 20,000:1. The flow path of the Quick Fixed Flow ter contains two fluid resistors that form a parallel flow path. Both low and high flow rate streams pass through fixed resistor cartridges. The ratio of these two resistors creates the split ratio. To understand how the Quick Fixed Flow ter works it helps to look at a diagram, figure 1, of the fluid resistors in relation to the flow paths and how a split ratio is calculated. Figure 1. Schematic flow diagram of the Quick Fixed Flow ter Input Flow - Q Resistor - L2 Low Flow Rate - Q2 Resistor - L1 High Flow Rate - Q1 L1 L2 R = Fixed fluid resistor (resistance value varies depending on cartridge rating) = Fixed fluid resistor (resistance value varies depending on cartridge rating) = ratio = Q1/Q2 = Resistance ratio = L2/L1 Since the flow rate is indirectly proportional to resistance, changing the resistance in either flow path results in a change to the split ratio. Changing resistance is accomplished by exchanging the fixed fluid resistor cartridges with a resistor set that has different resistor ratings. The Quick Fixed Flow ter is shipped with resistors installed that deliver the nominal stated split ratio. The split ratios have a tolerance range of +/- 10 %. The exact split ratio is measured at ASI and is stated on the certificate shipped with the splitter. The input flow rate can be adjusted to compensate for the tolerance in split ratios. For instance, a 10 % increase in input flow rate will result in a 10 % increase in flow at both the low and high flow channels. Flow rate and viscosity changes will change the backpressure generated by the splitter, but will not affect the actual split ratio. The Quick Fixed Flow ter is shipped configured for either post-column or pre-column applications. 4

5 Post-Column Applications Post-column splitting is fairly straight forward. Devices contribute to chromatographic dispersion so care must be given to connecting tubing and fittings, especially at low flow rates. The pressure drop specification for all input flow ranges is 500 PSI with water at the corresponding inlet flow rate respectively. To assure a maximum pressure drop of 500 PSI across the splitter, please specify the inlet flow when the splitter is ordered. ters are shipped complete with fluid resistors installed. Quick TM Binary Fixed Flow ter This easy to use plug and play device comes with a predefined split ratio eliminating tedious adjustments to capillary tubing. ratio changes are accomplished by changing the resistor set. The split ratio is determined by the ratio of fluid resistors installed in the splitter manifold. The pressure drop across a fixed splitter for post column applications is typically low, less than 500 PSI. The low internal dead volume prevents excessive dispersion and the replaceable inlet filter insures robust operation. Available in models for analytical, semi-preparative, preparative and high-preparative inlet flow rates. Interchangeable Fluid Resistor Cartridge & Ratios ratios and resistor cartridges other than those listed can be ordered to custom configure the Quick Fixed Flow ter.

12 Pre-Column Applications Pre-column splitting is used for micro, capillary, and nano HPLC applications, where the flow from the pump is split from analytical flow rates down to microliter or nanoliter flows. It is important to note that even though the split ratio created by the splitter valve will remain constant, the split ratio will change when a HPLC column is installed. This is due to the added resistance on the low flow rate channel from the HPLC column. This added resistance must be factored in to make sure the fluid resistors selected for the flow splitter provide the correct split ratio. Please contact ASI if you need assistance. ters are shipped complete with fluid resistors installed. When ordering a pre-column flow splitter please provide ASI with the column flow rate and back pressure. If the inlet flow rate or column pressure specification is not provided, ASI will configure pre-column flow splitters assuming a 0.5 ml/min. splitter inlet flow rate and a pressure drop across the column of 1,500 PSI. Adjustments to the low flow rate channel can be made by increasing or decreasing the splitter inlet flow rate.! Please consider Pre-column Adjustable Flow ters on page 23 when you need more than one split ratio. Quick TM Binary Fixed Flow ter This easy to use plug and play device comes with a predefined split ratio eliminating tedious adjustments to capillary tubing. ratio changes are accomplished by changing the resistor set. The split ratio is determined by the ratio of fluid resistors installed in the splitter manifold.

15 Quick TM Makeup-Flow ter Manifolds The ASI Quick Makeup-Flow ter Manifold is designed for post-column applications where a small amount of flow from an HPLC column is efficiently combined with a makeup-flow before it reaches the detector. Although there are many variations of this type of application, one of the most common involves splitting a small portion of the outlet flow from a preparative HPLC column which is then combined and diluted with a makeup-flow. The combined makeup-flow is used by a detector, typically Mass Spectrometry or UV, to trigger fraction collection from the remaining flow. A minimum delay time of 5 seconds (maximum inlet flow) is built into the splitter to insure proper seuencing between detection and fraction collection. Uniue integral resistor design eliminates tees and fittings within the splitter, resulting in extremely low peak dispersion. An additional binary splitter (see page 5) can be added after the manifold to allow splitting the makeup-flow stream prior to entering the detector. configuration orders must include inlet flow, split ratio, and delay time. In order to assure <500 PSI pressure drop across the splitter, please specify the inlet flow when you order. Inlet from Preparative HPLC Column Makeup Inlet R2/R1?
