필터 종류에 따른 호흡성 분진 농도 분석의 정전기 영향 = Electrostatic Effect of Weighting of Respirable Suspended Particulate According to the Types of Filter

다국어 초록 (Multilingual Abstract)

Quality assurance for fine particle requires conditioning of filters at 20∼23℃ and 30∼40% relative humidity for 24hr prior to gravimetric analysis. The reason for these requirements is that the accuracy or reliability of filter weighting is associated with and can be affected by several factors including temperature, humidity, light, draft, and electrostatic charge. In this study, concentration of respirable suspended particulate by gravimetric method was measured in smoking room by three kinds of filters (PVC, MCE and PTFE) to quantify the effect of electrostatic charge. Among the filters, MCE filter was statistically affected by electrostatic charge (p= 0.002).
