QuickSplit™ Binary Fixed Flow Splitters

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 maximum with water at the calibration flow rate. When ordering, please specify the actual inlet flow rate if it is significantly different from the calibration flow rate. Splitters are shipped complete with fluid resistors installed.

This easy to use “plug and play” device comes with a predefined split ratio eliminating tedious adjustments to capillary tubing. Split 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 and preparative inlet flow rates.

Custom Split Ratios

Split ratios and resistor cartridges other than those listed can be ordered to custom configure the QuickSplit™ Fixed Flow Splitter. Please contact ASI technical support for additional information about custom splitters. We will gladly assist you in determining the best splitter configuration for your application.

QuickSplit™ Binary Fixed Flow Splitters

Analytical Splitters - Binary

Analytical range, 0.1mL/min. to 5 mL/min.  input flow, calibration flow 1.0 mL/min.

These splitters will produce under 500 PSI backpressure with water at 1 .0 mL/min.* The backpressure will decrease or increase in proportion to flow rate changes. In order to assure <500 PSI pressure drop across the splitter, please specify the inlet flow when you order. Please see the accessory page for optional mounting bracket.

Analytical Replacement Resistor Sets - Binary

Semi-Preparative Splitters - Binary

Semi-Prep range, 5mL/min. to 40 mL/min. input flow, calibration flow 20 ml/min.

These splitters will produce under 500 PSI backpressure with water at 20.0 mL/min. The backpressure will decrease or increase in proportion to flow rate changes. The Semi-prep Fixed Flow Splitter HS (High Split Ratio) incorporates a resistor set which includes an ASI fluid resistor on the high flow side and a capillary resistor on the low flow side. In order to assure <500 PSI pressure drop across the splitter, please specify the inlet flow when you order. Please see accessory page for optional mounting bracket.

Semi-Preparative Replacement Resistor Cartridges - Binary

Preparative Splitters - Binary

Prep range, 30 mL/min. to 200 mL/min. input flow

These splitters will produce under 500 PSI backpressure with water at the specified inlet flow rate. The backpressure will decrease or increase in proportion to flow rate changes. In order to assure <500 PSI pressure drop across the splitter, the inlet flow rate must be specified when you order. Please see accessory page for optional mounting bracket.

Preparative Replacement Resistor Set - Binary

High-Preparative Splitters - Binary

High-Prep range, 200 mL/min. to 1,000 mL/min. Input flow

These splitters will produce under 500 PSI backpressure with water at the specified inlet flow rate. The backpressure will decrease or increase in proportion to flow rate changes. In order to assure <500 PSI pressure drop across the splitter, inlet flow rate must be specified when you order. Please see accessory page for optional mounting bracket.
