Description / Abstract:
This part of ISO 16000 specifies a determination of formaldehyde
(HCHO) and other carbonyl compounds (aldehydes and
ketones)1) 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 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[12],[16]. The
method is not suitable for longer chained or unsaturated carbonyl
compounds.
