<p>ISO 22155:2005 specifies a static headspace method for quantitative gas chromatographic determination of volatile aromatic and halogenated hydrocarbons and selected aliphatic ethers in soil.</p>
<p>ISO 22155:2005 is applicable to all types of soil.</p>
<p>The limit of determination is dependent on the detection system used and the quality of the methanol grade used for the extraction of the soil sample.</p>
<p>Under the conditions specified in ISO 22155:2005, the following limits of determinations apply (expressed on the basis of dry matter):</p>
<ol><li>when using gas chromatography with a flame ionization detector (GC-FID), the typical limit of determination is 0,2 mg/kg for volatile aromatic hydrocarbons, and 0,5 mg/kg for aliphatic ethers as methyl <i>tert</i>-butyl ether (MTBE) and <i>tert</i>-amyl methyl ether (TAME);</li><li>when using gas chromatography with an electron capture detector (GC-ECD), the typical limit of determination is 0,01 mg/kg to 0,2 mg/kg for volatile halogenated hydrocarbons. </li></ol>
<p>Lower limits of determination can be achieved by using mass spectrometry (MS) with selected ion detection.</p>
