1 Attenuation MethodPM10/2.5 Automated Dichotomous Monitor Model SPM-613DSPM continuous particulate analyzer developed by joint patent with Japan Science and Technology department of government,Kimoto and Tisch EnvironmentalBlack Carbon feature originated from work of DRI/EPA and measurement of OC/EC2FeaturesAmbient PM2.5,or fine fraction is what medical and epidemiological researcher are concerned about for health effects Ambient PM10,PM2.5 and Optical Black Carbon can be measured simultaneously on continuous basis.PM Coarse is calculated and reported as PM10-PM2.5=PMCUse of virtual impactor enables two measurements of both Fine and Coarse particles simultaneously with a Japan patented system*Monitor uses proprietary fluorocarbon membrane filter which reduces gas and moisture effect to minimum,and assures high sensitivitySample spots on fluorocarbon membrane filter useful for analyses of ion components and metal components after mass and Carbon direct measurement3Structure of SPM-613D4Virtual Impactor PM10 and PM2.5 Simultaneously5Validation and Calibration Device for Particle Size-Cut TestingParticle generator and aerosol mixing chamber to test inlet separators and virtual impactors for size-cut and penetration curves6Cut off curves7Fig.1 Comparison of Virtual Impactor vs WINS Impactor.(1-hour value)Fig.2.Comparison of SPM-613D vs EPA FRM sampler.(24-hour average)WINS vs.VI and FRM vs.Continuous8Fig.3.Comparison of GRIMM,TEOM(at 50 controlled)vs SPM-612D.(-hour value)Fig.4.Comparison of EC by DRI method vs OBC by SPM-613D.(1-hour value)9Fig.5.A daily plot of continuous ambient PM measurements10Element analysis11Time series Chemical Compositon12Gas and Particles13N&S14Winter Time Series/Chemical composition15Summer Time series/Chemical compositoin16Sampling time comparisons
