Versions in movement prices in the cell stage have an effect on the elution time of sample factors and end in mistakes. Pumps provide a continuing stream in the cell phase to your column under frequent pressure.
Peak width is the time from the start of your signal slope to achieving the baseline following repetitive drops while in the detector sign.
