ATDS-10A Automatic Thermal Desorption Test Machine

Introduction

ATDS-10A fully automatic thermal desorption instrument is a new generation of fully automatic thermal desorption instrument with fully automatic design, touch-screen display, more convenient operation and continuous operation of 10 samples. Normal temperature secondary desorption components or low temperature secondary desorption components can also be added according to user requirements.

Main function

1. Can automatically run 10 samples without personnel on duty;

2. Startup self-test, fault alarm and prompt, automatic positioning and calibration of sample disk using independent technology;

3 computer program control, the main functions are:

(1) Method parameter setting, real-time animation display working state and running time;

(2) The desorption area, sampling valve, sample transmission tube and secondary desorption area are heated and controlled separately;

(3) Set the analysis program and press the “Run” button to automatically complete all sample analysis;

(4) Normal temperature secondary desorption parts or low temperature secondary desorption parts can be added according to user requirements;

(5) GC and chromatographic data processing workstation can be started synchronously, and the device can also be started by external programs;

4. The machine has the function of standard sample simulation sampling, which can be more convenient to make the working curve through the thermal desorption instrument;

5. The sample tube activation program can be loaded to automatically activate the sample tube after desorption;

6. Through time programming, automatic desorption, purge adsorption, re-desorption, sampling, backblow cleaning and other functions are realized;

7. Electronic refrigeration and second-order thermal desorption processes are used to ensure a narrow chromatographic peak shape;

8. The sample transfer tube and sampling valve have automatic backblowing function to avoid cross contamination of different samples;

9. In order to support the use of imported gas chromatograph more convenient and accurate, the instrument is also equipped with a special interface for various imported instruments, easy connection;

10. For the analysis of active substances, elastic quartz tube can be selected as the sample transfer tube;

11. The needle is easy to change and can be connected to all types of GC injection ports at home and abroad.
