Characteristics and main functions of automatic thermal desorption desorption instrument
Automatic thermal desorption instrumentBy combining dual electronic control six way valves and solenoid valves, it is possible to program and automatically complete the four processes of primary desorption, secondary low-temperature enrichment, secondary desorption, injection, and blowback of 20 adsorption tubes in dual channels. The primary desorption temperature, secondary desorption temperature, cold trap temperature, and pipeline heating temperature can be independently set, and synchronous signals can be output during injection to simultaneously start chromatography and workstation.
Characteristics and main functions of automatic thermal desorption desorption instrument:
1. The automatic thermal desorption desorption instrument can automatically run up to 20 samples without the need for personnel on duty;
2. Power on self-test, fault alarm and prompt, automatic thermal desorption desorption instrument adopts independent technology to automatically locate and calibrate the sample disk;
3. Microcomputer program control, with main functions including:
⑴ Method parameter setting, real-time animation display of working status, and running time;
⑵ The desorption zone, injection valve, sample transfer tube, and secondary desorption zone are all separately heated and temperature controlled;
⑶ Set up the analysis program and pressAutomatic thermal desorption instrumentThe run button automatically completes all sample analysis;
⑷ Normal temperature secondary desorption components or low-temperature secondary desorption components can be added according to user needs;
⑸ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started using external programs;
4. The automatic thermal desorption desorption instrument comes with the function of simulating and sampling standard samples, which makes it more convenient to create working curves through the thermal desorption instrument;
5. The built-in sampling tube activation program can be loaded to automatically activate the desorbed sampling tube;
6. The automatic thermal desorption instrument can automatically achieve functions such as desorption, blow adsorption, re desorption, sample injection, and backwash cleaning through time programming;
7. The automatic thermal desorption instrument adopts electronic refrigeration and second-order thermal desorption process to ensure narrow chromatographic peak shape;
8. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;
In order to facilitate the use of imported gas chromatographs, the automatic thermal desorption desorption instrument is also equipped with interfaces for various imported instruments, which are easy to connect;
10. For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;
11. The injection needle is easy to replace,Automatic thermal desorption instrumentCan connect to GC injection ports of all models both domestically and internationally.
