Abstract People routinely working with chemicals in their workplaces would be exposed to more volatile organic compounds (VOCs) and at higher concentrations than in other environments during the workdays. VOCs commonly encountered in the workplace can exert various forms of acute and chronic health effect, depending upon the particular chemical along with its exposure time and concentration. Therefore, monitoring those VOCs on-site can help ensure the safe and healthful condition and guide an immediate first aid for workers. Traditional airborne VOC on-site monitoring methods require longer sample times and an external lab, which may not provide results for several days following the exposure event. Here, a fully automated portable comprehensive 2-dimensional (2-D) gas chromatography (GC) device (60 cm × 50 cm × 10 cm and <5 kg) was reported for the rapid and sensitive analysis of VOCs. Compared to the conventional portable GC, the unique design of the comprehensive 2-D GC architecture significantly enhances the peak capacity while maintaining compact size. In this work, the field analysis of indoor VOCs in real-time with a 1x4-channel 2-D GC device was described at the Spray and Finishing Shop of the University of Michigan, and the comparison to traditional methods of occupational VOC monitoring.
