Method ID-125G Wipes

Metal and Metalloid Particulates by ICP


This method describes the collection and subsequent analysis of airborne metal and metalloid particulate by Inductively Coupled Argon Plasma-Atomic Emission Spectroscopy (ICAP-AES). This method provides rapid simultaneous analysis and data reduction for a wide range of elements, eliminating the necessity of separate analyses by conventional atomic absorption techniques. A calibrated personal sampling pump is used to draw a known volume of air through a mixed-cellulose ester membrane filter contained in a styrene cassette. Filters are digested with sulfuric acid and hydrogen peroxide. Dissolution of the elements is facilitated by addition of hydrochloric acid. Analysis is performed using Inductively Coupled Argon Plasma-Atomic Emission Spectroscopy (ICAP-AES).
