Secondary thermal analyzer wholesale manufacturers teach you how to buy secondary thermal analyzer
The secondary thermal desorption instrument is a secondary thermal desorption instrument with an electronic cold trap. The gas circuit adopts an electric six-way valve, an eight-way valve and a solenoid valve. It can be programmed to automatically complete the four processes of primary desorption cold trap enrichment, secondary desorption, sample injection and backflushing of the adsorption tube. The cold trap temperature, primary desorption temperature, secondary desorption temperature and pipeline heating temperature can be set independently, and synchronous signals are output during sample injection, and the chromatography and workstation can be started at the same time.

The working principle of thermal analyzer
The thermal analyzer is a sample pretreatment device in the gas chromatograph analysis and detection system. It mainly uses physical methods to heat and adsorb the sample, so as to achieve the purpose of purifying the sample. Then, why should the sample be pretreated?
