Primary aliphatic amine-based probes

WebAqueous amines can be used as standards. The method was useful for calculating short-term exposure limits (STEL). A sampling time of 15 min at 30 ml min −1 was employed. Good recoveries for amines alone and their mixtures were obtained from air and water samples, 98±14 and 97±12% (mean value ± standard deviation), respectively. WebA new fluorescent reagent, 1-(1H-imidazol-1-yl)-2-(2-phenyl-1H-phenanthro[9,10-d]imidazol-1-yl)ethanone (IPPIE), is synthesized, and a simple pretreatment based on ultrasonic-assisted derivatization microextraction (UDME) with IPPIE is proposed for the selective derivatization of 12 aliphatic amines (C1: methylamine-C12: dodecylamine) in complex matrix samples …
