Brief introduction: Thermal desorption injection is currently one of the most advantageous and widely used sample pretreatment injection methods in gas chromatography (GC/MS) analysis. ATDS-3430 one-time semi-automatic thermal desorption sampling instrument is a product that the company has innovated and replaced in recent years on the basis of the research and development, production, sales and service of sample thermal desorption sampling device. During the research and development of the new product, the implementation of the new and old national standards and the needs of existing customers have been fully considered, and the functionality and work efficiency of the product have been greatly improved. This product can be used in conjunction with the current mainstream imported and domestic GC and GCMS. There are a variety of gas and circuit access schemes for users to choose. ATDS-3430 one-time semi-automatic thermal desorption sampling instrument contains a number of independent research and development technologies. ATDS-3430 one-time semi-automatic thermal analysis sampling instrument is not only suitable for advanced laboratories of scientific research institutes, but also suitable for those specialized fields (environmental monitoring, food and beverage, safety and forensic criminal investigation, cosmetics, agriculture, etc.) as routine analysis or monitoring instruments Matching selection. Features: 1. The rotary valve switching multi-dimensional gas path sampling system completely overcomes the shortcomings of domestic six-port and ten-port valves, such as short life and high temperature resistance. 2. The design of the gas path process is very simple, reliable, good for leak prevention, and greatly improves work efficiency. 3. The gas path through which the sample passes and the sample valve adopt inert treatment technology. 4. The gas path is optional (EPC electronic pressure control), and the digital display is more intuitive. It can realize automatic gas circuit system leak detection and fault alarm. 5. Adjust the injection volume through the injection time, which has been analyzed for samples of different concentrations. 6. For various standards, up to 10 methods can be stored. 7. Full-color screen display, friendly interface, touch operation, can be quickly and easily mastered, the whole process of tracking display operation process, set parameter values and real-time values, etc. 8. Expand the scope of services: ⑴ It can provide customers with experimental device schemes, technical consultations or co-construction and sharing of related projects for chromatographic analysis sample pretreatment. ⑵ Pyrolysis apparatus, functional module/unit combination and related parts, accessories, etc. can be bought, rented or exchanged for new.
