Air in workplaces - Determination of inorganic acids by ion chromatography - Part 2: volatile acids, except hydrofluoric acid (hydrochloric acid, hydrobromic acid and nitric acid)

Summary

This document specifies a method for determining the time-weighted average mass concentration of hydrogen chloride (HCl) gas and hydrochloric acid mists, hydrogen bromide (HBr) gas and hydrobromic acid mists and in vapors and mists of nitric acid (HNO3) in the air of workplaces, by sampling on an alkaline quartz fiber filter and analysis by ion chromatography. In the case of mist sampling, this method is applicable to individual sampling of the inhalable fraction of particles suspended in the air, as defined in ISO 7708, as well as to fixed point sampling.
