Fuel samples are collected by bubbling them through a entice which contains an appropriate solvent. Natural and organic isocyanates in industrial atmospheres are collected by bubbling the air via an answer of one-(2-methoxyphenyl)piperazine in toluene. The response between the isocyanates and one-(two-methoxyphenyl)piperazine the two stabilizes the
