ATD-1StypeSecondary thermal desorptionceremonyIt is a secondary (with low-temperature focusing cold trap) thermal analyzer independently developed and produced by our company. It is a secondary analyzer that integrates sampling, adsorption, desorption, injection, and cleaning. It adopts a new technology of sample tube desorption, low-temperature focusing, and hot air flow desorption. The 7.0-inch intelligent color touch screen user interface can easily set or edit, store, and call methods, quickly start analysis, and operate more conveniently, achieving the problem of low resolution rate.
