Abstract
The separation and detection of 22 carbamates and related compounds including insecticidal or herbicidal materials, in current use, were investigated on polyamide layers. Suitable solvent systems and the R F data obtained were reported. A new spray reagent, Pinacryptol Yellow, was examined for the detection of these compounds and its usability was ascertained. A comparison was also made between the detection limits by UV absorption on polyamide and silica gel layers, and the superiority of the polyamide layers was confirmed.
