ATDS-3440S Automatic Secondary Thermal Analysis Testing Machine
Description
Thermal analysis sampling is one of the most widely used sampling methods in gas chromatography (GC/MS),This product can be used in combination with the inlet of the current main flow and GC and GCMS made in China. There are a variety of gas and electric connections for users to choose,it is not only suitable for advanced laboratories of scientific research institutes, but also more suitable for those specialized fields (environmental monitoring, food and beverage, safety and forensic criminal investigation, cosmetics, agriculture, etc.) as routine analysis or Supporting selection of monitoring instruments
ATDS-3440S Automatic Secondary Thermal Analysis Testing Machine
Innovation points:
1. The rotary valve switching multi-dimensional gas path sampling system overcomes the disadvantages of domestic six-way and 10-way valves, such as short service life and inability to withstand high temperature.
2. The gas path process design is very simple, reliable, conducive to leakage prevention, greatly improve the work efficiency.
3. Inert treatment technology is adopted in the gas path and sample valve that the sample passes through.
4. Optional gas path (EPC electronic pressure control), digital display is more intuitive. It can realize automatic gas path system leak detection and fault alarm.
5. By adjusting the injection time, the sample has been analyzed for different concentrations.
6. For various standards, can store 10 methods.
7. Full color screen display, friendly interface, touch operation, can be quickly and easily mastered, the whole tracking display operation process, set parameter value and real time value.
8. Expand the scope of services:
(1) Provide customers with experimental equipment solutions, technical consultation or co-construction and sharing of chromatographic analysis sample pretreatment related projects.
⑵ Pyrolyzer, functional module/unit assembly and related parts and accessories can be bought, rented or trade-in.
Application field
1. Composition of volatile aroma and flavor compounds in food, and determination of residues and pollutants in food.
2. Composition of thermally degradable compounds in solid substrates, such as plasticizers, additives, monomers, etc. (These sample degradation products are desorbed by adsorption thermal desorption
Analysis and determination are helpful to the detection of arson cases).
3. Unwanted components in the sample matrix, such as residual solvents in pharmaceuticals, residual monomers in polymers, and other oligomers.
4. Purposefully collect volatile components in the sample matrix, such as polluted atmosphere, salt and sugar. At present, the typical application is to collect the volatiles in the air with adsorption tube
Machine pollutants (benzene series, VOCs) are used to monitor the environment.
5. A thermal analysis, generally only used for lower boiling temperature components (C2 ~ C13), inorganic and gas is not easy to do. If using low temperature adsorption trap (secondary thermal analysis)
Can achieve boiling point < C36 volatile samples.
6. It can also be used for special solids and liquids (such as dipping cotton into the tube).
7. Secondary adsorption thermal desorption sampling combined with GC/MS, has a wider range of applications, can solve the analysis and determination of complex types of samples, including environment, material, combustion
Material resources, food, pharmaceuticals, polymers and a variety of other commodities, etc.
