<p>ISO 22155:2011 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 22155:2011 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 22155:2011, the following limits of determination apply (expressed on the basis of dry matter):</p>
<p>Typical limit of determination when using gas chromatography/flame ionization detection (GC/FID):</p>
<ul>
<li>volatile aromatic hydrocarbons: 0,2 mg/kg;</li>
<li>aliphatic ethers as methyl <i>tert</i>-butyl ether (MTBE) and <i>tert</i>-amyl methyl ether (TAME): 0,5 mg/kg.</li>
</ul>
<p>Typical limit of determination when using gas chromatography/electron capture detection (GC/ECD):</p>
<ul>
<li>volatile halogenated hydrocarbons: 0,01 mg/kg to 0,2 mg/kg.</li>
</ul>
<p>Lower limits of determination can be achieved for some compounds by using mass spectrometry (MS) with selected ion detection.</p>
