Summary

A gas Chromatographic procedure for the analysis of carbamates is described. A specially prepared reaction tube, packed with a 10 % mixture of potassium hydroxide in glass beads, is placed inside the injection port of a Perkin-Elmer 900 Gas Chromatograph, in front of the Chromatographic column packed with Porapak Q. S.

A solution of the carbamates (0.01–0.1μmol) is injected directly into the gas Chromatograph. The carbamates are reacted with the alkali present in the reaction tube and the alcohols produced are separated, detected and recorded. Standard calibration graphs of the alcohols are prepared in the same manner and the quantities of carbamates are determined. The procedure is fast and quantitative.

Zusammenfassung

Ein gaschromatisches Verfahren für die Analyse von Carbamaten wurde beschrieben. Ein spezielles Reaktionsrohr, beschickt mit 10% iger Kalilauge auf Glasperlen, wird innerhalb der Injektionsöffnung eines Gaschromatographen Perkin-Elmer 900 vor dem mit Poropak Q. S. gefüllten Chromatographierohr angebracht. Die Carbamatlösung (0,01 bis 0,1 μMol) wird direkt injiziert. Die Carbamate reagieren mit dem im Reaktionsrohr befindlichen Alkali, die dabei entstandenen Alkohole werden getrennt, nachgewiesen und registriert. In gleicher Weise ermittelte Standard-Eichkurven der Alkohole dienen zur Bestimmung der Carbamate. Das Verfahren ist rasch und quantitativ.
