ATDS-440S type secondary fully automatic thermal analysis sampler

ATDS-440S type secondary fully automatic thermal analysis samplerInnovation point:

1. The rotary valve switches to a multi-dimensional gas injection system, completely overcoming the drawbacks of domestic six way valves and ten way valves, such as short service life and inability to withstand high temperatures.

2. The design of the pneumatic process is very simple, reliable, and conducive to leakage prevention, greatly improving work efficiency.

3. The gas path and sample valve through which the sample passes have been treated with inerting technology.

4. The air circuit can be optionally equipped with EPC electronic pressure control, and the digital display is more intuitive. It can achieve automatic gas path system leak detection and fault alarm.

5. By adjusting the injection time to adjust the injection volume, we have analyzed samples of different concentrations.

6. For various standards, 10 methods can be stored.

7. Full color screen display, user-friendly interface, touch operation, can be quickly and easily mastered, tracking and displaying the operation process, set parameter values, and real-time values throughout the process.

8. Expand service scope:

⑴ We can provide customers with experimental device plans, technical consultation, or co construction and sharing for chromatographic analysis sample pretreatment projects.

⑵ Pyrolysis apparatus, functional modules/unit assemblies, and related components, accessories, etc. can be purchased, rented, or exchanged for new.

ATDS-440S type secondary fully automatic thermal analysis samplerGeneral application areas:

1. The composition of volatile aroma and flavor compounds in food, and the determination of residues and pollutants in food.

2. The composition of thermally degradable compounds in solid matrices, such as plasticizers, additives, monomers, etc. in polymer materials (the degradation products of these samples are determined by adsorption thermal desorption analysis, which is helpful for the investigation 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 use adsorption tubes to collect volatile organic pollutants (benzene derivatives, VOCs) in the air for environmental monitoring.

5. A single thermal analysis is generally only used for lower boiling point temperature components (C2~C13), and inorganic and permanent gases are not easy to perform. If a low-temperature adsorption trap (secondary thermal analysis) is used, it can achieve a boiling point<C36 for volatile samples.

6. It can also be used for special solids or liquids (such as soaking cotton and placing it in a tube).

7. The combination of secondary adsorption pyrolysis and GC/MS has a wider range of applications, which can solve the analysis and determination of complex types of samples, including environment, materials, fuel resources, food, pharmaceuticals, polymers, and various other commodities.
