Lloyd R. Snyder (1931-2018): A Personal Tribute
December 1st 2018Lloyd Snyder was one of perhaps ten “founding fathers” of high performance liquid chromatography (HPLC), with seminal publications in most areas, including adsorption (normal phase), reversed phase, isocratic, gradient, and preparative chromatography; plus solvent, temperature, and column selectivity. With nine books, several hundred publications, and an h-index of 83, he was one of the most widely cited chromatographers and received many of the most prestigious awards in separation science.
