Comparison of Flow Rates
Chromolith® Prep columns for preparative chromatography can be operated with a flow rate of up to 400 mL/min, and pressures of up to 100 bar. This presents a tenfold increase in flow rate compared to particulate packed columns of an equivalent size.
Separation at different flow rates: 40 and 390 mL/min
