Thermal Desorption

Thermal desorption instruments are essential tools in sample preparation, enabling the extraction and analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) from various matrices. These systems typically operate by heating a sample, releasing trapped analytes which are then concentrated and transferred to an analytical instrument, such as a gas chromatograph (GC) or gas chromatograph-mass spectrometer (GC-MS), for identification and quantification. This technique simplifies complex sample preparation workflows for environmental monitoring, food safety testing, and materials science research, enhancing the sensitivity and accuracy of subsequent analyses. Leading manufacturers like Markes International, PerkinElmer, and Gerstel offer a range of thermal desorption systems with varying capacities and functionalities to suit specific application requirements.

Leading manufacturers like Markes International, PerkinElmer, and Gerstel offer a range of thermal desorption systems with varying capacities and functionalities to suit specific application requirements. Thermal desorption offers distinct advantages for applications requiring pre-concentration of trace-level analytes. It allows for analysis of a wider range of compounds compared to traditional solvent extraction methods, minimizing sample loss and improving detection limits. Common techniques using thermal desorption include analyzing air samples for pollutants, determining residual solvents in pharmaceuticals, and characterizing volatile emissions from polymers. Instruments like the Markes UNITY-xr, PerkinElmer TurboMatrix, and Gerstel TDS series are designed for automated and precise thermal desorption analysis, contributing to improved data quality and streamlined laboratory workflows in diverse scientific fields. - Less
