Product details
TD-3800 fully automatic thermal desorption instrument
The TD-3800 model has 10 sample grades, while the TD-3800B model has 20 sample grades
Introduction to fully automatic thermal desorption instrument:
The fully automatic thermal desorption instrument is a new generation of fully automatic thermal desorption instrument with fully automated design, touch screen display, and more convenient operation, capable of continuously running 10 samples. Normal temperature secondary desorption components or low-temperature secondary desorption components can also be added according to user needs.
The fully automatic thermal desorption instrument can be used with all imported and domestic gas chromatographs, and can meet the following standards:
1. HJ/644-2013 Determination of volatile organic compounds in ambient air - Adsorption tube sampling - Thermal desorption gas chromatography-mass spectrometry method;
2. HJ/T400-2007 Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles;
3. GB/T18883-2002 Indoor Air Quality Standards;
4. HJ/583-2010 Solid Adsorption/Thermal Desorption Gas Chromatography;
5. GB/50325-2010 Code for Indoor Environmental Pollution Control of Civil Building Engineering;
6. HJ 734-2014 Determination of volatile organic compounds in fixed source exhaust gas by solid-phase adsorption thermal desorption/gas chromatography-mass spectrometry, etc.
Characteristics and main functions of fully automatic thermal desorption instrument:
1. It can automatically run up to 10 samples without the need for personnel on duty;
2. Power on self-test, fault alarm and prompt, using independent patented 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 press the run button to automatically complete the analysis of all samples;
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 machine comes with the function of simulating and sampling standard samples, which makes it more convenient to create working curves through a thermal desorption instrument;
5. The built-in sampling tube activation program can be loaded to automatically activate the desorbed sampling tube;
6. Through time programming, automatic functions such as desorption, blow adsorption, re desorption, injection, and backwash cleaning can be achieved;
7. Adopt 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;
9. In order to make it more convenient and accurate to use with imported gas chromatographs, this instrument is also equipped with dedicated 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 and can be connected to all models of GC injection ports at home and abroad.
