Addressing the challenges of microplastic characterisation using thermal desorption
4 Dec 2020In this application note, Markes International demonstrate the quantitative analysis of microplastics using direct thermal desorption (TD) combined with gas chromatography–mass spectrometry (GC–MS). Direct desorption of filtrates containing microplastics provides a simple and streamlined sample preparation step while GC–MS analysis produces informationrich volatile organic compound (VOC) profiles. The VOC profiles contain marker compounds to identify and quantify the plastic, along with other chemical signatures that could prove useful in source apportionment, toxicity assessment and regional profiling.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ChromatographyChromatography is a powerful technique used to separate and analyze components of mixtures based on their chemical properties. It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
