Measuring system for organic substances that are insoluble or have a limited solubility
This system functions as follows: filtered river water is fed over a resin column for 24 hours. The organic substances bind to the resin.
Following this, the organic substances are eluated (soaked off) from the resin and separated in a gas chromatograph using a capillary column and identified using gas chromatography - mass spectrometry (GC-MS). The chromatogram can be used to determine whether any abnormal levels of organic substances are present. If the peaks in a chromatogram are clearly higher than the alert value, something must be wrong. The exact substance will then be determined and its concentration. This will determine the extent of the contamination and which measures are required.
