中文摘要 | an improved reagent named 2-[2-(dibenzocarbazole)-ethoxy] ethyl chloroformate (dbcec-cl) for the determination of aliphatic amines by high-performance liquid chromatography (hplc) with fluorescence detection and post-column online atmospheric chemical ionization-mass spectrometry (apci-ms) identification has been developed. dbcec-cl could easily and quickly label aliphatic amines. derivatives were stable enough to be efficiently analyzed by hplc and showed an intense protonated molecular ion corresponding m/z [m+h](+) under apci-ms in positive-ion mode. the ratios for fluorescence responses were i(dbcec-amine)/i(bce-amine) = 1.02-1.60; i(dbcec-amine)/i(bceoc-amine) = 1.30-2.57: and i(dbcec-amine)/i(fmoc-amine) = 2.20-4.12 (here, i was relative fluorescence intensity). the ratios for ms responses were ic(dbcec-amine)/ic(bcec-amine) = 4.16-29.31 and ic(dbcec-amine)/ic(bceoc-amine) = 1.23-2.47 (here, ic: apci-ms ion current intensity). detection limits calculated from 0.0244 pmol injection, at a signal-to-noise ratio of 3, were 0.3-3.0 fmol. the relative standard deviations for within-day determination (n=6) were 0.045-0.081% for retention time and 0.86-1.03% for peak area for the tested aliphatic amines. the mean intra- and inter-assay precision for all amine levels were <3.64% and 4.67%, respectively. the mean recoveries ranged from 96.9% to 104.7% with their standard deviations in the range of 1.80-2.70 (rsds%). excellent linear responses were observed with coefficients of >0.9991.
