TDS-100RD dual channel automatic secondary thermal analyzer

TDS-100RD dual channel automatic secondary thermal analyzer

Thermal Desorption (TD) is based on the principle that the sample to be measured (volatile and semi-volatile components) are adsorbed in a sampling tube with adsorbent material for enrichment, then heated to the sampling tube to desorb the volatile and semi-volatile components from the adsorbent material, and carried the desorbed components into the gas chromatography for analysis. The thermal desorption/desorption unit is a device used to achieve the thermal desorption/desorption sampling. Based on whether the volatile and semi-volatile components are desorbed from the sampling tube and then concentrated by cold focusing, the thermal desorption unit is divided into a primary and a secondary thermal desorption unit. The sample components desorbed from the sample tube were concentrated and enriched in the secondary thermal desorption unit. The sample components after concentration were imported into the gas chromatography with a small amount of gas to improve the sampling efficiency and obtain a better peak shape spectrum.

Product Description

A fully automated thermal analyzer is actually a combination of technologies that extract volatiles from a complex matrix and concentrate them for GC or GC/MS analysis. For gas samples, such as air, a convenient method is to extract a known volume from a thermal desorption tube containing one or more sorbents. In other words, air can be extracted into an evacuated container. Other samples (e.g., polymers, food, packaging materials, etc.) can be placed directly into thermal desorption tubes or larger containers.


As a solvent-free extraction technology for gas chromatography, automatic thermal analysis instrument has been widely used. This technology is characterized by high sensitivity, speed and simplicity, and a wide range of use. It is suitable for the analysis of volatile and semi-volatile organic compounds in air and materials compatible with gas chromatography, including: air, semiconductor materials, polymers, interior decoration, furniture packaging materials, drugs, and flavor analysis and testing; The analysis range can include organic compounds with volatility greater than n-C40 and small amounts of inorganic compounds.

 

 

It can be applied in a variety of fields

It is limited to laboratory scientific research use and may not be used for other purposes.

PRODUCT FEATURES

The thermal desorption instrument runs fully automatically, and the sample analysis and injection process is automatically completed with one button.
It can be linked with all brands of gas chromatography systems on the market to automatically complete the desorption injection analysis process of samples.
Bidirectional linkage with gas chromatography system. When the GC system fails, thermal resolution stops the injection, which effectively protects the sample and avoids repeated sampling.
The rapid loading system completes the sealing and heating action in one step, and the loading process does not require any sealing caps.
The tightness of the pipeline is automatically detected before analysis, and the sample tube with leakage is not injected, which effectively protects the sample and avoids repeated sampling.
Fully inert gas path control, independent temperature control valve box, to ensure the low detection of the system and not easy to contaminate.
Patented cryogenic capture high-temperature flash evaporation device for easy excellent chromatographic response and peak shape.
Graphical control menu, easy to use, can store 20 method sequence files, each time directly recall the method file can be used.
