Top Guidelines Of types of hplc detectors
Gas samples are collected by bubbling them by way of a trap that contains an appropriate solvent. Organic isocyanates in industrial atmospheres are gathered by bubbling the air as a result of a solution of one-(2-methoxyphenyl)piperazine in toluene. The reaction between the isocyanates and one-(two-methoxyphenyl)piperazine both stabilizes them in o
