Contaminated sites pose a threat to the environment and human beings. The contamination often exists in form of volatile organic compounds and therefore can be encountered in the gas phase in soils. Gas samples for later analysis are taken on site in proof of soil contamination in different depths. At the TUHH a sampler was developed, which is inserted with an auger into the soil to receive gas with commercially available medical syringes. The system allows to receive up to six fabric samples from different drilling depths. The syringes are analyzed at the surface. Since the soil contamination often exists in form of volatile organic compounds, photoionization detectors with an ionization potential of 10.6 eV are very well suited for the analysis. In combination with a gas chromatographic separation stage gas mixtures can also be analyzed.
