RS ISO 17943: 2016
Water quality — Determination of volatile organic compounds in water — Method using headspace solid-phase microextraction (HS-SPME) followed by gas chromatography-mass spectrometry (GCMS)

Abstract

(see Table 1). This comprises, for example, halogenated hydrocarbons, trihalogenated methanes,
gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane,
and highly odorous substances like geosmin and 2-methylisoborneol in drinking water, ground water,
surface water, and treated waste water, by means of headspace solid-phase micro-extraction (HS-SPME)
followed by gas chromatography-mass spectrometry (GC-MS). The limit of determination depends on
the matrix, on the specific compound to be analysed, and on the sensitivity of the mass spectrometer.
For most compounds to which this International Standard applies, it is at least 0,01 ?g/l. Validation
data related to a concentration range between 0,02 ?g/l and 2,6 ?g/l have been demonstrated in an
interlaboratory trial. Additional validation data derived from standardization work show applicability
of the method within a concentration range from 0,01 ?g/l to 100 ?g/l of individual substances. All
determinations are performed on small sample amounts (e.g. sample volumes of 10 ml).
This method may be applicable to other compounds not explicitly covered by this International Standard
or to other types of water. However, it is necessary to demonstrate the applicability for each case.
