Gel permeation chromatography [PDF]
Endeavour, 1984 Abstract Gel permeation chromatography is the most valuable single technique in the molecular weight characterisation of polymers. The power of this technique lies in its ability to give information on the whole molecular weight distribution. In Britain, the Polymer Supply and Characterisation Centre provides a GPC service for research workers in the

Oxalate-silica gel thin-layer system for free 2-hydroxy fatty acids and for fatty acyl coenzyme A
Journal of Lipid Research, 1972 The 2-hydroxy fatty acids tend to yield streaks in thin-layer chromatography on silica gel plates. If potassium oxalate is included with binder-free silica gel, good spots are obtained.
