We’ll learn how to find the “sweet spot” in terms of retention for a liquid chromatography separation as well as how much retention change can be expected for a selected change in mobile-phase percent organic or column temperature. LCGC 35(4) 240-245 (2017) John W. Dolan See also 2017-3 and 2017-5 […]
Read More →When considering column efficiency, more is not always better. We look at some ways to quickly estimate the effects of changes in column length and particle diameter rather than trying the experiments in the laboratory. LCGC 35(3) 170-173 (2017) John W. Dolan See also 2017-4 and 2017-5 for remaining articles […]
