Introduction: ATDS-3430 Thermal Desorption Apparatus is a new generation product that our company independently developed and launched directly for the majority of users at home and abroad. This instrument is suitable for the qualitative and quantitative detection of various gases with boiling points below 350℃ in chemical building materials, food, atmosphere and indoor environments. It can be connected to any domestic and foreign gas chromatographs and gas-mass spectrometers. Its degree of automation, Indicators such as repeatability and sensitivity can fully meet the current environmental testing standards newly promulgated by the country, and it has its own unique functional advantages and satisfactory performance and price ratio in terms of structure. Fully automatic design, large touch screen display, more convenient operation. Features: 1. Use semiconductor refrigeration to save cost, electronic refrigeration and second-stage thermal desorption process to ensure a narrow chromatographic peak shape; 2. All sample transfer pipelines adopt imported high-inert deactivation pipelines, with no residue and no cross-contamination, ensuring the repeatability and accuracy of sample injection; 3. The machine comes with the function of standard sample simulation sampling, which can make the working curve by the thermal desorption instrument more conveniently; 4. Using high temperature six-way valve, the operating temperature can reach 240℃; 5. Through time programming, functions such as desorption, purge adsorption, re-desorption, sample injection, backflush cleaning, etc. are automatically realized; 6. Electronic refrigeration and second-stage thermal desorption process are used to ensure narrow chromatographic peak shapes; 7. The sample transfer tube and injection valve have automatic backflushing function to avoid cross-contamination of different samples; 8. In order to match the imported gas chromatograph to be more convenient and accurate to use, this instrument is also equipped with special interfaces for various imported instruments, which is convenient to connect; 9. The connection point between the six-way valve and the transmission pipeline is in the heating and incubator, and there is no cold spot for transmission, which ensures the integrity of the sample; 10. The injection needle is easy to replace and can be connected to all types of GC injection ports at home and abroad; 11. Integrated design, compact structure; microcomputer control, 7-inch LCD display in Chinese, simple and convenient operation.
