A fully automated portable comprehensive 2-dimensional (2-D) gas chromatography (GC) device was utilized for the first time for the field analysis of occupational volatile organic compounds (VOCs) at the Spray and Finishing Shop of the University of Michigan. The instrument contains a full set of micro-preconcentrator/injectors, commercial columns, micro-Deans switches, micro-thermal injectors, micro-photoionization detectors, data acquisition cards, and power supplies, as well as computer control and user interface. The indoor air was sampled and analyzed before, during, and after spraying the five most frequently used paints. The 2-D analysis yields enhanced peak capacity and shortened analysis time as compared to those achieved by portable GC instruments reported to date. In addition, the portable system is able to perform on-site analysis of VOCs, providing the results every 5 to 15 min, which would allow for enhanced acquisition of information regarding workers' safety and health risks from airborne VOCs. The performance of the portable 2-D GC device was validated by comparing the quantitative results of various type of paints using traditional occupational VOCs monitoring techniques in accordance with Occupational Safety and Health Administration Method ORG-07.

便携式全面二维气相色谱仪对职业中挥发性有机化合物的暴露进行现场监测†

密歇根大学喷雾与精加工车间首次使用全自动便携式二维（2-D）气相色谱（GC）装置进行职业挥发性有机化合物（VOC）的现场分析。该仪器包含全套微型预浓缩器/进样器，商业色谱柱，微迪恩斯开关，微型热进样器，微型光电离检测器，数据采集卡和电源，以及计算机控制和用户界面。在喷涂五种最常用的涂料之前，之中和之后对室内空气进行采样和分析。与迄今为止报道的便携式气相色谱仪相比，二维分析可提高峰容量并缩短分析时间。此外，便携式系统能够对VOC进行现场分析，每5至15分钟提供一次结果，从而可以更好地获取有关机载VOC中有关工人安全和健康风险的信息。通过根据职业安全与健康管理方法ORG-07，使用传统的职业VOC监测技术比较各种类型涂料的定量结果，从而验证了便携式2-D GC设备的性能。
