Column Performance Test Parameters

This test combines the three basic phases necessary for a run (equilibration, sample

application, and elution). After equilibrating the column, a non-adsorbing sample,

such as acetone or salt, is injected via the sample loop and eluted under isocratic

conditions. After the run, calculate the column efficiency in terms of height

equivalent to a theoretical plate (HETP) and the peak asymmetry factor (As).
