For surface wipe sampling, contact Laboratory Customer Service. The analytical results are expressed as total chromium. Cassettes 913 or 916, whose filters are preweighed, can also be used. For surface wipe sampling, contact Laboratory Customer Service. The analytical results are expressed as total chromium. Chromium VI, water insoluble inorganic compounds (as Cr) 0,01 C1 RP EM S 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.
