Flow Splitters (QuickSplit™)

    QuickSplit™ Flow Splitters create accurate, reproducible split ratios using two or more fluid resistors in parallel flow paths.  These fluid resistors are available in a wide range of values, making ratios of 1:1 to 20,000:1 possible.  Our fluid resistors have extremely low internal volume.  Delay volume on the splitter’s low side is as low as 100 nanoliters, depending on resistor cartridge selected. Low internal dead volume prevents excessive dispersion.  While changes in flow rate and viscosity will affect the splitter’s back pressure, viscosity changes associated with gradient runs DO NOT impact the split ratio for post-column applications.  Because of very low fluid resistor internal volume, solvent composition in both resistors at any instant in time is the same.

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