OSHA Method ID-105: Inorganic Arsenic in Workplace Atmospheres
Description
Inorganic arsenic particulate in the air is collected by drawing a known volume of the air through a 0.8-µm mixed-cellulose ester (MCE) filter and backup pad using a calibrated personal sampling pump. A chemically-treated backup pad is used if volatile inorganic arsenic species are suspected. If arsine is also suspected, a sampling train is used (see Section 5). Wipe and bulk materials are collected using grab sampling techniques.
