What is NIOSH Method 7405 for Alkali Cations about?

This document describes a method for measuring alkali metal cations (sodium, potassium, lithium) in air samples. Samples are collected on quartz fiber filters then extracted with sulfuric acid. The extract is analyzed by ion chromatography with conductivity detection. The method was evaluated over a range of 0.08-7.2 mg/m3 and found to have negligible bias and overall precision of <22% for all three cations. It provides a specific measurement of the cations as hydroxides or their corresponding salts in air.
