31、ard is applicable to all types of soil.NOTE In the case of unsaturated peaty soils, absorption of the extraction solution may occur.The lower limit of determination is dependent on the equipment used and the quality of the methanol grade used for the extraction of the soil sample.Under the condition

32、s specified in this International Standard, the following limits of determinations apply (expressed on a basis of dry matter):a) Typical limit of determination when using gas chromatography/flame ionization detection (GC/FID): volatile aromatic hydrocarbons: 0,1 mg/kg.b) Typical limit of determinati

33、on when using gas chromatography/electron capture detector (GC/ECD): volatile halogenated hydrocarbons: 0,01 mg/kgLower limits of determination for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection.2 Normative referencesThe following referenced documents are

39、en 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. After centrifugation, part of the methanol extract

40、is brought into a purge vessel filled with water. The volatile compounds are purged with nitrogen or helium and adsorbed on a suitable adsorbing agent. The adsorbed compounds are desorbed thermally and by means of a carrier gas flow, whether or not via a cold trap, brought into a gas chromatograph.

41、The various compounds are separated by using a capillary column with an immobile phase of low polarity. Volatile organic compounds are detected with appropriate detectors such as: mass spectrometric detector (MS), flame ionization detector (FID), electron capture detector (ECD), photo ionization det

42、ector (PID) or electrolytic conductivity detector (ELCD). Identification and quantification takes place by comparison of retention times and peak heights (or peak areas) towards an internal standard added with the corresponding variables of an external standard solution. The efficiency of the proced

43、ure depends on the composition of the soil that is investigated. The described procedure does not take into account incomplete extraction caused by structure and composition of the soil sample.When using non-specific detectors such as FIDs and ECDs, the confirmation of the identity of the detected c

44、ompounds 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.NOTE 1 This International Standar

45、d follows the description of an off-line purge-and-trap method. The use of commercial available online instruments is allowed, provided that equivalent results are obtained during validation of this equipment. With such an instrument, purge and trap occurs on line with gas chromatography and detecti

46、on. Follow the manufacturers manual, especially regarding the items composing the apparatus which are listed in 5.1.1 to 5.1.9.NOTE 2 Other injection techniques, such as static headspace followed by thermal desorption (ISO 22155) or solid-phase micro-extraction (SPME), can be used, provided that the

47、ir applicability is proven.4 ReagentsAll reagents shall be of recognized analytical grade. Verify whether the reagents are applicable for this specific purpose and free of interfering compounds.4.1 Water, free of volatile aromatic and volatile halogenated hydrocarbonsUsually boiler water with a temp

48、erature of at least 80 C and 1 day old can be applied. Purging with an inert gas, e.g. a flow of 10 ml/min of nitrogen for 30 min, is another means of removing interfering compounds from water. A sufficient amount of water from the same batch should be available to complete each batch of analyses, i

49、ncluding all preparations.4.2 Internal standard compounds4.2.1 For the determination of volatile aromatic hydrocarbons, preferably two internal standard compounds shall be selected that do not interfere with compounds present in the sample extract.Examples of suitable internal standards are toluene-D8 (CAS RN 2037-26-5),
