Brief introduction ATDS-3420S thermal desorption autosampler device following a number of innovations , improvements and refinement:
1 . Just add the necessary "function module" I can achieve a variety of sample processing functions to achieve " one" injection analysis ;
2 . Single-page , digital, touch control, large-size LCD screen to replace the multi-page , thin film key input , small-size LCD screen display
3 . Gas pressure to achieve digital display , to improve the accuracy of analysis to provide a guarantee ;
4 . Increasing the pressure change when the sample thermal desorption monitoring function.
5 . Expanded use of silicone rubber insulation material , so that the injection conduit heater temperature was raised above 250 ℃, particularly advantageous for the analysis of high boiling point ; Features 1. The function module is integrated design, compact structure, easy operation and maintenance ;
2. Computer touch control, single-page LCD character display, digital input
3. With pressurized gas regulation and digital display system without any modification to the GC instrument and change the instrument does not need to adjust the original carrier gas , and other parameters can be carried out by thermal desorption analysis of the high-pressure injection ;
4. resolve tube mounting pressure sensors and pressure sealing performance digital display ;
5. At the same time for several GC injection analysis , greatly improving the work efficiency ;
6. automatically pressurized , sampling, sampling, analysis, and analysis of the purge function; 7. Use a high-pressure injection principle ( no six -way valve and quantitative tube ) reduces the adverse effects of the injection valve , at the same time improve the analysis
Sensitivity ;
8. Samples of sampling and sample transfer tube are automatic purge function, to avoid cross-contamination of different samples ;
9. For the analysis of the active substance optional 0.53mm elastic quartz tube as the sample delivery tube ;
