Remarks Stibine (as Sb) 7803-52-3 0,51 Silica gel tube impregnated with mercuric 0,01- 50 UV/VIS-S NIOSH 6008 bichloride 0,2 Contact the IRSST before sampling. Stoddard solvent 8052-41-3 525 SKC 226-01 activated charcoal tube Max: 10 GC-FID 275 5,0 IRSST 80-1 2120 Activated charcoal 100/50 mg 0,2 A process sample must be supplied. Strontium chromate (as Cr) 7789-06-2 0,0005 C2 RP EM PALL CA28149-306 vinyl/acrylic copolymer filter 926 Vinyl/acrylic copolymer filter 1,5 à 4 360 IC-VIS 0,04 4,4 IRSST 365 For surface wipe sampling, contact Laboratory Customer Service. The analytical results are expressed as total water-insoluble chromium VI. Surface tests for chromates can be carried out, and the required equipment (kit #2625) is available at the IRSST. See communiqué 2008-06 on our Web site. Analysis time of 8 days for welding fumes and 10 days for the other processes following the sampling date. Ship all samples by rapid courier within a period not exceeding 24 hours after sampling. Any substance that produces a response on the detector at 540 nm and that has a retention time similar to Cr VI is a potential interference. Strychnine 57-24-9 0,15 Glass fiber filter 1-3 200 HPLC-UV NIOSH 5016 Contact the IRSST before sampling. Styrene (monomer) 100-42-5 213 426 Pc C3 DRI-PAD IRSST 39-A Refer to the user's guide accompanying the instrument. Styrene is quantified in the field with a direct-reading instrument (DRI). The minimum reported value is of 0.5 mg/m³ (0.12 ppm). The reference method corresponds to calibration of the DRI. Styrene (monomer) 100-42-5 213 426 Pc C3 3M Organic Vapor Monitor #3500 2695 Passive dosimeter 0,0289 GC-FID 27 1,4 IRSST 31-3 For the monitors, the flow must be considered as being a sampling rate. According to the data from 3M, the precision (CVsampling) of the sampling rate is 3.0%. Refer to the 3M passive monitor guide on the IRSST's Web site. Styrene (monomer) 100-42-5 213 426 Pc C3 SKC 226-01 activated charcoal tube 2120 Activated charcoal 100/50 mg Max: 0,2 5 3 GC-FID 27 1,4 IRSST 31-3 The analysis can be done by gas chromatography coupled with mass spectrometry (GC-MS, IRSST method #369); in this case the analytical uncertainty (CVa) is 3.0%. Subtilisins (Proteolytic enzymes as 100 % pure crystalline enzyme) -- -- 0,00006 RP Contact the IRSST before sampling. No supporting reference is suggested for this product.
