Integrated solution for the monitoring of impurities in liquid matrices by Gas Chromatography using a simplified and enhanced headspace sampling system.
Chromatotec® presents a headspace sampling system designed to extract representative samples from the liquid phase. The vaporized sample can be preconcentrated using a trap to achieve quantification at very low concentration levels (ppb and/or ppm). Then, it is injected automatically and in continuous mode into the auto-GC analyzer. Speciation of sulfur compounds or VOCs is done with a MEDOR® sulfur specific electrochemical detector or an FID respectively.
The complete system allows online analysis without human intervention and without gas cylinders thanks to gas generators.
VOCs in water
Auto GC-FID and GC-MS for water monitoring
Sulfur compounds in water
In option, for : Water surveillance, with sulphur in air in option Waste water plant River water Rain water Sea water
Polymer (acrylonitrile) analysis
In aqueous mode, it has been applied for the analysis of acrylonitrile. This polymer is used in plastics, fibers or as a component of additives to enhance oil recovery. This sampling system reduces the risk of polymerization of its monomer, acrylamide, avoiding the clogging of the column.
Oil and gas market
It allowed controlling the effectiveness of the LPG odorization process with DMS and TBM, to alert in case of leakage in safe and hazardous areas.
