Gasoline samples are gathered by bubbling them by way of a lure which contains an acceptable solvent. Organic isocyanates in industrial atmospheres are collected by bubbling the air by way of a solution of 1-(two-methoxyphenyl)piperazine in toluene. The response amongst the isocyanates and 1-(2-methoxyphenyl)piperazine both equally stabilizes them
