[82 KB, PDF] Monitoring Methods used by OSHA Laboratory Sampling/Analytical Method: sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 microns maximum volume: 960 Liters   minimum volume: 480 Liters   maximum flow rate: 2.0 L/min (TWA) current analytical method: Inductively Coupled Argon Plasma; ICP/DCP-AES method reference: OSHA Analytical Method (OSHA ID-125G) method classification: Fully Validated note: Multi-element analysis for 13 metals is possible on a single filter. The metals are: Cobalt, Beryllium, Molybdenum, Cadmium Chromium, Copper, Iron, Manganese, Nickel, Lead, Antimony Vanadium and Zinc. Metal Oxide compounds are reported for the convenience of the industrial hygienist and are based on the elemental concentration multiplied by the appropriate gravimetric conversion factor. If the total weight of sample needs to be determined, evaluate gravimetrically using the method for Particulates not otherwise regulated (Total Dust). It is all right to submit Low Ash Polyvinyl Chloride (LAPVC) filters for ICP analysis after doing the Gravimetric analysis. All Trademarks are the property of their respective owners.
