Experimental data are presented to help understand HPLC column retention in a way that should make column selection and method development proceed faster when initial results with C18 columns are disappointing.

Guest columnist Dick Henry traces the history of HPLC back more than 40 years, starting with his days at DuPont.

As LC-UV and LC-MS have become preferred instrumental methods for fast, sensitive analysis, many scientists are searching for ways to optimize performance.
