  1. WBEAPassive Sampler Validation Studyfor NH3 and HNO3 Compare Ogawa and Radiello PS with ADS Use the following specific adsorbing material: Sodium chloride and Nylon for HNO3 Citric and phosphorous acid for NH3 Assess DL, precision & accuracy at 2 sites: AMS01 Fort McKay (FMK), AMS06 Fort McMurray (FMM) Expose monthly for total 5 months Start on June 1 , 2011

  2. Samplers and Components Annular Denuder System (ADS) Ogawa PS CA - SCL - NYL Inlet Box Filter Pack Denuder Coupler / End-cap (shipping) 2/3 Denuders SCL - CA/PA Impactor Coupler Elutriator Acceleration Jet for PM2.5 Left & Right Collection Pad analyzed together (composite) Radiello PS PA Adsorbent Cartridge Diffuser Sample Flow ADS inlet is positioned at same height above ground as all PS units !!

  3. Sample Media Required for Months 1 - 2 ADS Passive Samplers (PS) Field Blank Lab Blank Lab Blank Field Blank FP1 FP2 DUP1 DUP2 RadPA1 RadPA2 RadPA0L RadPA0F OgaCA0L OgaCA1 OgaCA2 OgaCA0F FP0 D3-PA1 D3-CA2 D3-PA0F D-PA0L OgaSCL2 OgaSCL0L OgaSCL0F OgaSCL1 D-CA0L D2-SCL1 D2-CA2 OgaNYL2 OgaNYL1 D-SCL0L D2-CA0F OgaNYL0L OgaNYL0F keep stored (1x) ship to each site (2x) D1-SCL1 D1-SCL2 Denuders, EI and FP are shipped separately and assembled in field prior to sampling. Field Blanks are treated like samples except that they remain unexposed. ADS inlets (EI1 and EI2) are positioned at exact same height above ground as the PS units. With each monthly shipment one set of Lab Blanks is prepared and stored in Lab until field media are being analyzed. D1-SCL0F cap ship to each site (2x) EI1 EI2 Coating solutions are 1% (w/w) in DI water: SCL …sodium chloride, CA …citric acid, PA …phosphorous acid; NYL …Nylon.
