Footnotes
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. Refer to the method for details.This SKC Air Sampling guide is a reference only to assist users in finding the method, sampling equipment, and sampling media for a specific compound. This publication is intended for general information only and should not be used as a substitute for reviewing applicable government regulations, equipment operating instructions, or legal standards. Users must consult the appropriate sampling method for the compound of interest before sampling. The sampling parameters shown here are suggestions based on the ranges or volume, flow, and time specified in the methods. It is the responsibility of the analyst performing the sampling and analysis steps to adjust the parameters so that the required detection limits can be obtained.
