AutoTD OLS online thermal desorption Introduction
Thermal desorption as a solventless extraction technique for gas chromatography has been used more and more widely. This technology features high sensitivity, fast and simple, and a wide range of applications. Suitable for the analysis of volatile and semi-volatile organic compounds in gas-compatible air and materials, including: air, semiconductor materials, polymers, interior decoration, furniture packaging materials, pharmaceuticals, and flavor analysis, etc.; analysis range can include volatility Organic matter larger than n-C40 and a small amount of inorganic matter. Features
Operating mode Single stage desorption, secondary (first stage desorption to secondary cold trap focusing and then quickly desorbed by cold trap), multiple desorption, sample tube activation
Adopt international standard sample tube, primary splitting * secondary split
Adsorption focus mode
Desorption method back-blowing desorption first-stage heating desorption cold trap hot air flow instantaneous desorption
Automatic leak test
One-button control automatic timing analysis
Touch screen operation, password protection, can save 10 methods. It has a universal interface and can be connected to any gas chromatograph. It can be controlled remotely through the IOS system.
Available in both Chinese and English.
