Brief introduction Thermal desorption solvent extraction technique as a non- GC has been more widely used. This technique has a high sensitivity , fast and simple , using a wide range of features. Suitable for air and gas chromatography -compatible materials in the volatile and semi-volatile organics analysis, including : air, semiconductor materials , polymers, interior decoration , furniture, packaging materials, drugs, and flavor analysis and detection , and so on ; the scope of analysis may contain volatile more than a small amount of organic and inorganic substances of n-C40 . Typical applications include : indoor air and urban air monitoring ; Forensic ; material composition analysis and dissemination ; food , flavor and aroma analysis . Features AutoTD series automatic thermal desorption - desorption instrument is successful AutoHS automatic headspace sampler platform developed on the basis of a new generation of thermal desorption - desorption instrument . With high sensitivity , good reproducibility and no memory effect advantage. And has a one-button control of automatic timing analysis is complete, touch screen operation , password protection, optional English , fault alarm and save 10 methods and so on. Interfaces with any gas chromatograph through a universal interface .
