Analysis of volatile organic compounds emitted from chemical parts and monitor set of PC/Monitor

Volatile organic compounds(VOCs) emitted from PC/Monitor set and chemical parts comprising of PC/Monitor set were analyzed and emission trends of VOCs on temperature were investigated. Qualitative analyses of VOCs from PC/Monitor set and chemical parts were carried out by residual gas analyzer(RGA) and GC-MS system, and quantitative analysis was achieved for toluene, cyclohexanone, benzofuran, and xylene of VOCs based on qualitative analysis. As a result of these analyses, when the Wedge Rubber of rubber product was heated from 60 .deg. C to 80 .deg. C, the emission rate(%) of xylene was increased about 2.5 times. But it was evaluated that the left of chemical parts were not affected by temperature except Wedge Rubber. The results of qualitative analyses between RGA and GC-MS were a little different respectively. With quantitative analysis, concentration of xylene emitted from cabinet was measured to be maximum as 6029.3 μg/m3(1.3ppm). The concentrations of toluene, xylene, and benzofuran derived from PC/Monitor set were 10.25 μg/m, 690 μg/m3, and 180 μg/m3, and these concentrations were relatively high levels which can bring on the risk to human health
