Separation and identification of parathion and its metabolites in autopsy tissues by thin layer chromatography

Summary Thin-layer chromatography on magnesium oxide/starch with 4% ethanol in fusel oil will distinguish parathion and its metabolitep-nitrophenol from malathion, diazinon andm-systox in autopsy fluids and tissues. As little as 1g of parathion can be detected on the thin-layer plate with Rhodamine B.

Zusammenfassung Dünnschiohtchromatographie auf Magnesiumoxid/ Stärkepulver mit Amylalkohol und 4% Ä hanol eignet sich zur Unterscheidung von Parathion und dessen Metaboliten p-Nitrophenol von Malathion, Diazinon und Metasystox in Körperflüssigkeiten und Geweben. 1g Parathion kann auf der Dünnschichtplatte noch mit Rhodamin B nachgewiesen werden.

Separation of homologous n-alkylammonium hexanoates by reverse-phase thin layer chromatography with continuous development

Long-chain n-alkylammonium hexanoates can be separated according to alkyl chain length by reverse-phase thin layer chromatography on commercially available plates with mixtures of acetonitrile, tetrahydrofuran, and formic acid as developing solvents. Differences in alkyl chain length of two carbon units can be resolved for chain lengths up to 22 carbon units. The use of continuous development for improving resolution has been investigated. An application to the characterization of a ¹⁴C-labeled alkyl-ammonium hexanoate is discussed.
