5.《GB/50325-202Indoor environmental pollution control in civil construction projectsstandard》；

6HJ734-2014 Determination of Volatile Organic Compounds in Waste from Fixed Pollution Sources by Solid Phase Adsorption/Thermal Desorption Gas Chromatography, etc.

IIInstrument features andmajor function

1. The new generation upgraded product features a stylish exterior design, optimized and restructured internal structure, and more accurate and reliable transmission and positioning.

2. Adopting a new electronic pressure sensor with real-time display of pressure status;

3. Can run automatically up to20 samples, no need for personnel on duty;

4Power on self-test, fault alarm and prompt;

5. Seven inch capacitive touch screenControl,Human computer interaction is more intuitive and comfortable:

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

(2)The desorption zone, injection valve, sample transfer tube, and secondary desorption zone are all separately heated and temperature controlled;

(3)Set up the analysis program and press the run button to automatically complete the analysis of all samples;

(4)Additional room temperature secondary desorption components can be added according to user needs;

(5)Can start synchronouslyGC、 The chromatographic data processing workstation can also be started with external programs;

6The 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;

7Through time programming, automatic functions such as desorption, blow adsorption, re desorption, injection, and backwash cleaning can be achieved;

8Low temperature secondary desorptionAdopting electronic refrigeration and second-order thermal desorption process to ensure narrow chromatographic peak shapes;

9The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;

10In order to provide more convenient and accurate use for imported GC and GCMS, this instrument is also equipped with dedicated interfaces for various imported instruments,Can connect all models both domestically and internationallyGC、GCMS；

11For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;

12. The injection needle is easy to replace and can be connected to all models of GC injection ports at home and abroad.
