angulatus venom was established by the neurological clinical symptoms observed in six mice inoculated Intraperitoneally with peak 3 of size exclusion chromatography
Writing for university students, academic researchers, and manufacturing quality analysts, he discusses such topics as methods for determining molar mass, light scattering instrumentation, size exclusion chromatography
measurements and data processing, characterizing complex polymers with multi-angle light scattering, the theory and basic principles of asymmetric flow field flow fractionation, and detecting and character branching.

A white paper titled, "Static Light Scattering Technologies for GPC/SEC Explained," available from the company, is said to be a valuable guide for anyone assessing the value of a light scattering detector for gel permeation/size exclusion chromatography
A newly available application note from Malvern Instruments explains why, when one is measuring samples using gel permeation chromatography/size exclusion chromatography
(GPC/SEC), low-angle light scattering (LALS) is the only LS technique that actually measures a scattered light intensity directly proportional to molecular weight.
