建立了同时测定室内外空气中脂肪胺和芳香胺的气相色谱-质谱（GC-MS）分析方法。该方法包括空气样品经酸性溶液净化预富集、磷酸二（2-乙基己基）酯（BEHPA）离子对萃取、氯甲酸异丁酯（IBCF）衍生化和GC-MS分析。以BEHPA为离子对试剂，将脂肪胺和芳香胺从水样中分离出来，用IBCF衍生化后进行色谱分析。然后用GC-MS在电子轰击（EI）和正负离子化学电离（PNICI）模式下分析脂肪族和芳香族胺作为其异丁氧羰基（isoBOC）衍生物。回收率为75.6%~96.8%，相对标准偏差（R.S.D.）在1.0 - 4.4%之间。通过使用基于S/N：3的GC-MS结果计算获得的检测限在0.08 - 0.01 ng/m（3）范围内。(c)2006 Elsevier B.V.保留所有权利。
A gas chromatography-mass spectrometry (GC-MS) method has been proposed for the simultaneous determination of aliphatic and aromatic amines in indoor and outdoor air samples. The method includes pre-concentration of the compounds by percolating the air samples through the acidic solution, ion-pair extraction with bis-2-ethylhexylphosphate (BEHPA), derivatisation of compounds with isobutyl chloroformate (IBCF) and their GC-MS analysis. Aliphatic and aromatic amines were isolated from aqueous samples using BEHPA as ion-pair reagent and derivatised with IBCF for their chromatographic analysis. Aliphatic and aromatic amines were then analysed with GC-MS in both electron impact (EI) and positive and negative ion chemical ionisation (PNICI) mode as their isobutyloxycarbonyl (isoBOC) derivatives. The obtained recoveries ranged from 75.6 to 96.8% and the precision of this method, as indicated by the relative standard deviations (R.S.D.) was within the range of 1.0-4.4%. The detection limits obtained from calculations by using GC-MS results based on S/N: 3 were within the range of 0.08-0.01 ng/m(3). (c) 2006 Elsevier B.V. All rights reserved.
