Gel and affinity chromatography

Abstract

H. L. James is a Project Leader in the Chemical Analysis section of the R&D division of the Standard Oil Company (Ohio). He is presently involved in Analytical Research and Method Development in the areas of polymers and petroleum. Recent research interests include developing liquid exclusion chromatographic methods for monitoring polymerization processes. Mr. James received his B.A. in chemistry from Syracuse University and his M.S. in polymer chemistry from the University of Akron. He is coauthor of ten scientific papers in various areas of polymer characterization, co-chairman of the Akron-Cleveland GPC/LC Discussion Group, co-editor of the ASTM Bibliography on Liquid Exclusion Chron phy, and a member of the American Chemical Society and Sigma Xi.

Gel permeation chromatography of low molecular weight materials with high efficiency columns

“…It has been used for the separation of surfactants (5), triglycerides (6), tall oil components (7), fatty acids (8), polyethylene glycol (9), and various other materials (10)(11)(12)(13)(14). In most of these cases the columns used were of considerable length and retention times were usually very long.…”

New analytical techniques for mycotoxins in complex organic matrices

“…It seems likely, therefore, that a single calibration curve (elution vs. some size parameter) is not possible for a wide variety of functional groups [60]. A survey of non-exclusion effects is given in two recent reviews on exclusion chroma tography [61,62].…”
