Workplace air. Determination of lithium hydroxide, sodium hydroxide, potassium hydroxide and calcium dihydroxide. Method by measurement of corresponding cations by suppressed ion chromatography Ingestion-build-44616 and human errors in use1 Scope This International Standard specifies a method for the determination of the time weighted average mass concentration of lithium hydroxide (LiOH), sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium dihydroxide [Ca(OH)2] in workplace air by collection of the particulate hydroxides on a filter and analysis of the corresponding cations using ion chromatography. For aerosol sampling, the method is applicable to the personal sampling of
