The secondary thermal analyzer is a secondary thermal desorption instrument with an electronic cold trap. The gas circuit adopts a combination of electric six-way valve, eight-way valve and 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.

Aspects to consider when choosing a secondary thermal analyzer:

Technical certification should 1. be considered: when we purchase a fully automatic secondary thermal desorption instrument, we must pay attention to check whether the certification data of the instrument is formal and complete, and whether it has the certification of the national analytical instrument quality supervision and inspection center and the national standard substance testing center.

2. technical parameters should be considered: the technical parameters of the automatic secondary thermal desorption instrument mainly include temperature control range, temperature control accuracy, analytical pressure, analytical time, sample injection time, analytical tube specifications and the use of voltage, etc., so it is necessary for us to understand the specific settings and ranges of its parameters, and to confirm whether these parameters meet the requirements and complete settings.

3., the price of the instrument should be considered: different brands of automatic secondary thermal analyzer may be different in price due to their different technologies. At this time, it is better to consider both the price and the technology. Choose a fully automatic secondary thermal desorption instrument with affordable price and guaranteed quality. In addition, you can also compare the spare parts and services of the product.

4., after-sales service should be considered: and comprehensive and good after-sales service can ensure that the automatic secondary thermal analyzer can be solved in time if problems occur. Therefore, it is necessary to have a detailed understanding and comparison of the warranty period, maintenance times, maintenance devices and maintenance services of the after-sales service of the instrument, and to choose from the after-sales service.
