Тезис

This part of ISO 16000 specifies a determination of formaldehyde (HCHO) and other carbonyl compounds (aldehydes and ketones) in air. The method is specific to formaldehyde but, with modification, at least 12 other aromatic as well as saturated and unsaturated aliphatic carbonyl compounds (see last paragraph) can be detected and quantified. It is suitable for determination of formaldehyde and other carbonyl compounds in the approximate concentration range 1 µg/m3 to 1 mg/m3. The sampling method gives a time-weighted average (TWA) sample. It can be used for long-term (1 h to 24 h) or short-term (5 min to 60 min) sampling of air for formaldehyde.

This part of ISO 16000 specifies a sampling and analysis procedure for formaldehyde and other carbonyl compounds that involves collection from air on to adsorbent cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis of the hydrazones formed by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption.

This part of ISO 16000 applies to the determination of: formaldehyde; acetaldehyde; acetone; benzaldehyde; butyraldehyde; valeraldehyde; 2,5-dimethylbenzaldehyde; capronaldehyde; isovaleraldehyde; propionaldehyde; o-tolualdehyde; m-tolualdehyde; p-tolualdehyde.
