QuickSplit™
Post-Column Adjustable Flow Splitters
- Post-column splitting is fairly straight forward. Like pre-column
flow splitting, any significant additional pressure (resistance)
down stream from the splitter may affect the split ratio. Post-column
devices also contribute to chromatographic dispersion so care must
given to connecting tubing and fittings, especially at low flow
rates.
-
- Use the back pressure vs split ratio chart on page 22 and 23
to select a QuickSplit
Adjustable Flow Splitter that will provide the desired
split ratio range and back pressure. These charts correspond to
several flow rates and solvent systems. The back pressure is directly
proportional to flow rate and viscosity. The back pressure estimates
on these charts only apply to post-column applications. Splitters
are shipped complete with the resistor cartridge installed.
-
- To assure optimum pressure drop across the splitter, please
specify the inlet flow when the splitter is ordered.
Custom Split Ratios
- Split ratios and resistor cartridges other than those listed
below can be ordered from
ASI
to custom configure the
QuickSplit Adjustable
Flow Splitter. Please contact technical support at 800-344-4340
for additional information about custom splitters. We will gladly
assist you in determining the best splitter configuration for your
application.
