Thin layer chromatography systems

Lipophilicity represents the affinity of a molecule or a moiety for a lipophilic environment. It is commonly measured by its distribution behavior in a biphasic system, either liquid-liquid (e.g. partition coefficient in 1-octanol-water) or solid-liquid (retention on reversed-phase high-performance liquid chromatography or thin-layer chromatography system).

Clarke [2] recommended the following three thin-layer chromatography systems [70]. [Pg.186]

Stohs and Scratchley (53) investigated several thin layer chromatography systems for thiazide diuretics and antihypertensive drugs, using silica gel G and a variety of detection reagents. [Pg.307]

Analysis by TLC. Confirmation of the identity of the halogenated compounds in the soil samples was achieved by resolution of selected extracts on TLC plates, followed by gas chromatography of the separate compounds eluted from the plates. The thin layer chromatography system of Kovacs (6) was used, and the halogenated compounds were detected with the silver nitrate-2-phenoxyethanol reagent. Comparison with standards chromatographed on the same plates permitted an estimate of the pesticide concentrations. [Pg.273]
