  1. Introduction to Tisch Instruments John Tisch Tisch Environmental

  2. TheβAttenuation methodPM2.5 Automated Dichotomous MonitorModel SPM-612D • Continuous PM analyzer developed by joint patent with Japan Science and Technology Corporation • Black Carbon feature originated from work of DRI/EPA and measurement of OC/EC

  3. Features • Ambient PM2.5 fraction is emphasis of medical, epidemiological researchers • Ambient PM10 or PM2.5 and optical black carbon can be measured simultaneously on a continuous basis. PM Coarse is calculated and reported as PM10 - PM2.5 = PMC • Use of virtual impactor uses two measurements of fine and coarse particles simultaneously • Monitor’s fluorocarbon membrane filter reduces gas, moisture effect to minimum, assures high sensitivity • Sample spots on fluorocarbon membrane filter are useful for analyzing ion components and metal components after mass and Carbon direct measurements
