Do you know the characteristics of purge and trap analysis?

How does the thermal analyzer work?

The thermal analyzer is a sample pretreatment device in the gas chromatograph analysis and detection system, which mainly uses physical means to heat and absorb the sample, so as to achieve the purpose of purifying the sample. So why pretreat the sample?

Buy a thermal analyzer to consider these factors!

Thermal desorption instrument has been widely used in life science research, industrial production, modern agriculture, environmental protection, pharmaceutical industry, tobacco industry, education and training, petrochemical, food, electronics and many other industries:

Analytical sampling technology is a widely used sampling technology, and the main equipment of thermal analysis sampling technology is thermal analyzer.

Implementation requirements for thermal analyzer

The thermal analyzer is a two-way automatic direct injection thermal analyzer. The gas circuit adopts the combination of electric six-way valve and solenoid valve, which can automatically program the desorption, injection and backwashing of the adsorption tube. The heating temperature of the adsorption tube and the heating temperature of the pipeline can be set independently, the synchronization signal can be output during injection, and the instrument can start the chromatography and the workstation at the same time.

Sample Injection Technology of Thermal Analyzer

Thermal analyzer is a kind of sample pretreatment device. The minimum concentration of organic compounds detected by GC or GC/MS can reach ppb or even ppt level. Thermal analyzer is a new type of thermal analyzer. Its advantages are that the recovery rate is close to 100% and the minimum detection limit is greatly reduced, thus ensuring the linear range, precision and accuracy of analysis.
