Abstract

The paper presents the application of a method based on coupled gas chromatography-mass spectrometry, using an isotopically labelled internal standard for the quantitative analysis of benzene (B), toluene (T), ethyl benzene (E), and o-, m-, p-xylenes (X). Their atmospheric concentrations were determined based on short-term sampling, in different sites of Cluj-Napoca, a highly populated urban centre in N-W Romania, with numerous and diversified road vehicles with internal combustion engines. The method is relatively inexpensive and simple and shows good precision and linearity in the ranges of 7-60 mug/m(3) (B), 13-90 mug/m(3) (T), 7-50 mug/m(3) (E), 10-70 mug/m(3) (X-m,p), and 20-130 mug/m(3) (X-o). The limits of quantitation/detection of the method LOQ/LOD are of 10/5 mug/m(3) (Xo), 5/3 mug/m(3) (B, E, X-m,p), and of 3/1 mug/m(3) (T), respectively.

摘要

本文介绍了一种基于气相色谱-质谱联用技术的方法在定量分析苯（B）、甲苯（T）、乙苯（E）和邻、间、对二甲苯（X）中的应用。该方法使用同位素标记的内标，通过短期采样，在罗马尼亚西北部人口众多的城市克卢日-纳波卡的不同地点，对大气中浓度进行了测定。该方法相对便宜且简单，在 7-60μg/m³（B）、13-90μg/m³（T）、7-50μg/m³（E）、10-70μg/m³（X-m，p）和 20-130μg/m³（X-o）范围内具有良好的精密度和线性。该方法的定量/检测限分别为 10/5μg/m³（Xo）、5/3μg/m³（B、E、X-m，p）和 3/1μg/m³（T）。
