Rapid Characterization of Small Amounts of Oil by Thin-Layer Silica-gel Chromatography

Naturevolume 193pages674675 (1962) | Download Citation



MOST methods for characterizing small amounts of oil (for example, 0.1–2.0 mgm.) are based on spectroscopic techniques. When chemical techniques are applicable they are time-consuming. There is a need for a simple method not requiring expensive apparatus and I have applied thin-layer silica-gel chromatography1. A review of some applications of this type of chromatography has recently been published2, and the apparatus for preparing the thin layers of absorbent is commercially available (Camlab (Glass), Ltd., Cambridge).
