SHIMSEN TD Tube
Thermal Desorption Thermal Desorption(short for TD) A process in which a substance is heated to a certain temperature to release the adsorbed compounds. TD is common- ly used as a preconcentration technique in gas chromatography(GC) to enable the analysis of low concentration compounds. The working principle of Thermal Desorption Firstly, volatile organic compounds(VOCs) or semi-volatile organic compounds(SVOCs) are collected on the adsorbent in the Thermal Desorption tube(TD tube). Then, the adsorbent is heated under a certain airflow to release these compounds, concentrating them into a smaller volume. Main Application Areas Indoor air quality monitoring Detection of fragrances and flavors VOCs detection in the environment Automobile interior air pollutants Emission testing from stationary pollution sources Gas detection from components and materials
