38、 Standard is applicable to all types of soil.The limit of quantification is dependent on the detection system used and the quality of the methanol grade used for the extraction of the soil sample.Under the conditions specified in this International Standard, the following limits of quantifications a
39、pply (expressed on basis of dry matter).Typical limit of quantification when using GC-FID: volatile aromatic hydrocarbons: 0,2 mg/kg; aliphatic 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 halogenat
40、ed hydrocarbons: 0,01 mg/kg to 0,2 mg/kg.Lower limits of quantification for some compounds can be achieved by using mass spectrometry (MS) 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

44、 (E) 5 3 PrincipleTest samples are taken from an untreated field moist soil sample. To prevent losses of the volatiles, 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
45、 the methanol extract is transferred into a headspace vial with a defined amount of water and sealed. The temperature 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 vo
46、latile compounds in gaseous phase in equilibrium with the water in the vials is carried out by using headspace injection and an appropriate capillary column. Volatile organic compounds are detected with appropriate detectors as, mass spectrometric detector (MS), flame ionization detector (FID), elec
47、tron capture detector (ECD), photo ionization detector (PID), or electrolytic conductivity detector (ELCD). Identification 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 an
48、d ECD, the confirmation of the identity of the detected compounds and their concentrations should be done by repeating 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.
