The work of preparing International Standards is normally carried out through ISO technical committee
21、s. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inter
22、national Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the diff
23、erent types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shal

Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is

28、method for quantitative gas chromatographic determination of volatile aromatic and halogenated hydrocarbons and selected aliphatic ethers in soil.This International Standard is applicable to all types of soil.The limit of quantification is dependent on the detection system used and the quality of th
29、e methanol grade used for the extraction of the soil sample.Under the conditions specified in this International Standard, the following limits of quantifications apply (expressed on basis of dry matter).Typical limit of quantification when using GC-FID: volatile aromatic hydrocarbons: 0,2 mg/kg; al
30、iphatic ethers as methyl tert.-butyl ether(MTBE) and tert.-amyl methyl ether (TAME): 0,5 mg/kg.Typical limit of quantification when using GC-ECD: volatile halogenated hydrocarbons: 0,01 mg/kg to 0,2 mg/kg.Lower limits of quantification for some compounds can be achieved by using mass spectrometry (M
31、S) with selected ion detection (see Annex D).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

To prevent losses of the volatile
35、s, samples are taken as undisturbed as possible in the field with a tube corer or by adding methanol immediately in the field.The test sample is extracted with methanol. An aliquot of the methanol extract is transferred into a headspace vial with a defined amount of water and sealed. The temperature
36、 of the vials is stabilized in a thermostatic system to a temperature within the range 50 C to 80 C to achieve specified equilibrium conditions. Gas chromatographic analysis of the volatile compounds in gaseous phase in equilibrium with the water in the vials is carried out by using headspace inject
37、ion and an appropriate capillary column. Volatile organic compounds are detected with appropriate detectors as, mass spectrometric detector (MS), flame ionization detector (FID), electron capture detector (ECD), photo ionization detector (PID), or electrolytic conductivity detector (ELCD). Identific
38、ation and quantification is made by comparison of retention times and peak heights (or peak areas) comparing to the internal standard added.When using non-specific detectors as FID and ECD, the confirmation of the identity of the detected compounds and their concentrations should be done by repeatin
39、g the gas chromatographic analysis using a column of different polarity. When using gas chromatography-mass spectrometry (GC-MS), the identity confirmation and the quantification can be done in a single run.4 ReagentsAll reagents shall be of recognized analytical grade.
