A major disadvantage of this instrument is the required long sampling time. Electrical low pressure impactor has been developed to overcome this disadvantage and to achieve real-time measurements on the particle size distribution. The instrument consists primarily of a corona charger, low pressure cascade impactor and multi channel electrometer. We designed and evaluated the performance of a potable 3-stage low pressure impactor using an electrical method. For the calibration of the impactor, monodispersed particles were generated using evaporation-condensation method followed by electrostatic classification using a DMA(Differential Mobility Analyzer). The collection efficiency curves of the stages can be determined by analysing the fraction of particles collected by each stage. 대한기계학회 미세입자 측정용 간이형 3단 전기적 저압 임팩터의 설계 및 성능평가 Design and Performance Evaluation of a Portable 3-Stage Electrical Low Pressure Impactor(P-ELI) for Measurements of Submicron Aerosol Article 2 대한기계학회논문집 B, v.28, no.7, pp.826 - 833 대한기계학회논문집 B 28 7 826 833 kci ART001095262 Electrical Low Pressure Impactor(전기적 저압 임팩터) Cascade Impactor(다단 임팩 터) Cutsize(분리입경) Stokes Number(스톡스 수) Electrical Low Pressure Impactor(전기적 저압 임팩터) Cascade Impactor(다단 임팩 터) Cutsize(분리입경) Stokes Number(스톡스 수)
