38、y and mass spectrometry3 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 methano

39、l. After centrifugation, if necessary, part of the methanol extract 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

40、, whether or not via a cold trap, brought into a gas chromatograph. 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 d

41、etector (FID), electron capture detector (ECD), photo ionization detector (PID) or electrolytic conductivity detector (ELCD). Identification and quantification takes place by comparison of retention times and peak heights (or peak areas) towards internal standard added with the corresponding variabl

42、es of an external standard solution. The efficiency of the procedure 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

43、FID and 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 quantificatio

44、n can be done in a single run.NOTE This International Standard follows the description of an off-line purge and trap method. The use of commercially available online instruments is allowed provided that equivalent results are obtained during validation of this equipment. With such an instrument purg

45、e and trap occurs on line with gas chromatography and detection. Follow the manual of the manufacturer especially regarding the items 5.2.1 to 5.2.9.4 ReagentsAll reagents shall be of recognized analytical grade. Verify whether the reagents are applicable for this specific purpose and free of interf

46、ering compounds.4.1 Water, free of volatile aromatic and volatile halogenated hydrocarbonsUsually boiler water with a temperature 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 compou

A sufficient amount of water from the same batch should be available to complete each batch of analyses, including all preparations.4.2 Internal standards4.2.1 For the determination of volatile aromatic hydrocarbons preferably two internal standards shall be selected from Table 1.
