This method is for the collection and analysis of oxalic acid from workplace air. The sample is collected on a glass fiber filter. After sample collection the extracted with 10mLs of a misture of 0.028M sodium hydroxide (NaOH) and analyzed by ion chromatography (IC).
NOTE: This is a partically validated method.
