Preparative liquid chromatography: sample volume overload

Optimization of sample size and sample volume in preparative liquid chromatography

“…One of the issues that has been addressed is how the volume affects the column height equivalent to a theoretical plate (HETP) (9). Various authors have calculated the maximum volume that can be injected in order for two peaks to just be resolved, but remaining in the linear elution chromatography (10)(11)(12). Snyder (3) points out that there is little influence of the sample volume in overloaded elution when the volume of the injection is less than half the volume of the band.…”
