Filter diameters and flow rates
Samplers 1 through 4 have 47 mm diameter filters they operate at a flow rate of 17 Liters per min MOUDI operates at a flow rate of about 30 Liters per min SDI operates at a flow rate of 11 Liters per min HiVol samplers have 102 mm diam. Filters flow rate: 320 Lpm (Hi flow) and 35 Lpm (Low flow) Analytical techniques PM gravimetric analysis for the particulate mass (PM) INAA instrumental neutron activation analysis (INAA): 40 elements, from Na upward PIXE particle-induced X-ray emission spectrometry (PIXE): over 20 elements, from Na upward IC ion chromatography TOT thermal-optical transmission (TOT) instrument for measuring organic carbon (OC) and elemental carbon (EC) TOC total organic carbon (TOC) analyser for measuring water-soluble organic carbon (WSOC) GC/MS gas chromatography / mass spectrometry
5
Aerosol collections from 9 September to 14 November 2002
8 samplers operated in parallel separate day and night samples mostly collected collection time per sample varied from 12 hours in September to up to 48 hours in November 80 collections with each sampler
