This part of ISO 16000 describes a procedure for the determination of formaldehyde (HCHO) *) and other carbonyl compounds *) (aldehydes and ketones) in air. The method is specific for formaldehyde but, with modification, at least thirteen other carbonyl compounds can be detected and quantified. It is suitable for determination of formaldehyde and other carbonyl compounds in the concentration range of approximately 1 ug/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 describes a sampling and analysis procedure for formaldehyde and other carbonyl compounds that involves collection from air onto cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption [1, 3].
The procedures described are written specifically for the sampling and analysis of formaldehyde in air using an adsorbent cartridge and HPLC. The method also permits the determination of other aldehydes and ketones collected from air.
This part of ISO 16000 is applicable to the following carbonyl compounds:
Formaldehyde
Benzaldehyde
2,5-Dimethylbenzaldehyde
Isovaleraldehyde
o-Tolualdehyde
Acetaldehyde
Butyraldehyde
Propionaldehyde
p-Tolualdehyde
Acetone
Valeraldehyde
Crotonaldehyde
Hexanal
m-Tolualdehyde
*) Instead of the nomenclature according to IUPAC regulations, the more common names are used in this International Standard:

acetone: 2-propanone
butyraldehyde: butanal
crotonaldehyde: 2-butenal
isovaleraldehyde: 3-methylbutanal
propionaldehyde: propanal
m-tolualdehyde: 3-methylbenzaldehyde
o-tolualdehyde: 2-methylbenzaldehyde
p-tolualdehyde: 4-methylbenzaldehyde
valeraldehyde: pentanal
