Omfang: This International Standard specifies two methods for the determination of highly volatile halogenated hydrocarbons using gas chromatography.
Section 2 specifies a method for the determination by liquid/liquid extraction of highly volatile halogenated hydrocarbons in drinking water, most rivers and lakes and many sewage and industrial effluents. Typical values of "quantification limits" are given in table 1.
(Table 1 - Typical values of "quantification limits" for some highly volatile halogenated hydrocarbons using liquid/liquid extraction)
Section 3 specifies a method for the determination of highly volatile halogenated hydrocarbons in drinking water, surface waters and ground water by a static headspace method. Typical values of "quantification limits" are given in table 2.
In practise, the head-space method is applicable for industrial effluents as a screening method, but in some cases it is necessary to confirm the result by the liquid-liquid extraction method.
NOTE: When applying this International Standard, the guide on analytical quality control for water analysis (see ISO/TR 13530) should be followed, especially for the calibration steps.
