Flow Heated Column Compartment
Columns:
1
For better separation in preparative Liquid ChromatographyEach parameter in the analytical LC is set and monitoredvery precisely. The temperature of the column is anessential factor for a good separation and is adjusteddepending on the problem and analytes. In the preparativefield, temperature control for columns has been thought of,but columns are only heated externally. For low flow ratesin the analytical field this might be sufficient, but forpreparative separations and high flow rates a lot ofefficiency is lost when the mobile phase is not heated.Lower mobile phase viscosityFaster interaction with stationary phaseLower system back pressureHigher flowrates without loosing resolutionShorter cycle timesEqualize the enthalpy of mixing solvents
