Introduction
BK-TD50A automatic thermal desorption device can be loaded into 50 position sample tube at a time with full load, and can be used with all domestic and imported GC and GCMS.
Feature:
1.Power on self-test, fault alarm and prompt function, temperature overload protection function, leakage protection function, gas path differential pressure alarm function, etc., which improves the safety factor of the instrument.
2. The sample position is up to 50, which can meet the daily sample analysis.
3. The adsorption tube can automatically take off the cap and put on the cap automatically, and automatically detect the gas path leakage.
4. Electronic pressure and flow display function.
5. The imported switching valve and solenoid valve are used for gas path control, which has stable performance and effectively prevents sample contamination.
6. All gas pipes have been passivated.
7. New human-computer interaction interface, separate function of detection method, real-time cloud chart display working state, running time, flow, etc;
8. The program control of sample coil position can realize the specified pipe position detection, and can add sample tube at any time according to the demand, which makes the detection process more flexible and smooth;
9. The GC and workstation can be started synchronously, and the anticontrol between GC and GC can also be realized;
10. The machine has the function of analog sampling of standard sample, which is convenient to obtain the working curve;
11. Low temperature secondary desorption function, using electronic refrigeration and two-stage flash thermal desorption process;
12. It has the function of sample diversion, which can prevent contamination of the instrument when detecting high concentration samples;
13. Add log, help, stopwatch and other functions to provide more convenience.
