<p>ISO 22155:2016 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 22155:2016 is applicable to all types of soil.</p>
<p>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.</p>
<p>Under the conditions specified in this International Standard, the following limits of quantifications apply (expressed on basis of dry matter).</p>
<p>Typical limit of quantification when using GC-FID:</p>
<p>- volatile aromatic hydrocarbons: 0,2 mg/kg;</p>
<p>- aliphatic ethers as methyl tert.-butyl ether(MTBE) and tert.-amyl methyl ether (TAME): 0,5 mg/kg.</p>
<p>Typical limit of quantification when using GC-ECD:</p>
<p>- volatile halogenated hydrocarbons: 0,01 mg/kg to 0,2 mg/kg.</p>
<p>Lower limits of quantification for some compounds can be achieved by using mass spectrometry (MS) with selected ion detection (see Annex D).</p>
