Description of 21/30427653 DC 2021This part of ISOÂ 16000 specifies a determination of formaldehyde (HCHO) and other carbonyl compounds (aldehydes and ketones)1 1 Instead of systematic IUPAC nomenclature, traditional names are used in this part of ISOÂ 16000. Some equivalent names are: acetaldehyde: ethanal / acetone: 2-propanone / butyraldehyde: butanal / capronaldehyde: hexanal / formaldehyde: methanal / isovaleraldehyde: 3-methylbutanal / propionaldehyde: propanal / m-tolualdehyde: 3-methylbenzaldehyde / o-tolualdehyde: 2-methylbenzaldehyde / p-tolualdehyde: 4-methylbenzaldehyde / valeraldehyde: pentanal. This part of ISOÂ 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[12],[16]. The method is not suitable for longer chained or unsaturated carbonyl compounds. This part of ISOÂ 16000 applies to the determination of:
