Chromatographic thermal desorption analyzer JX-4 semi-automatic dual channel primary thermal analyzer

Semi automatic dual channel one-time thermal analyzer

JX-4

Chromatographic thermal desorption analyzer JX-4 semi-automatic dual channel primary thermal analyzerApplication Overview:

The JX-4 thermal analyzer is a dual channel one-time thermal analyzer that can analyze two samples simultaneously, doubling the efficiency. It has three functions: standard sample simulation sampling, thermal analysis, and analysis tube activation. The temperature of the analysis, injection valve box, and injection pipeline can be controlled separately without any cold spots, ensuring the integrity of the sample. Easy to operate, one click start, automatic process completion. Can be used in conjunction with domestic and imported gas chromatographs. Suitable for fields such as occupational health and environmental monitoring. Applicable to the following standards: "HJ 583-2010 Determination of Benzene Compounds in Environmental Air Solid Adsorption Thermal Desorption Gas Chromatography Method"; GB 11737-1989 Hygienic Inspection Standards for Benzene, Toluene, and Xylene in the Atmosphere of Residential Areas - Gas Chromatography Method; GB 50325-2020 Code for Indoor Environmental Pollution Control of Civil Building Engineering includes "Determination of Benzene in Indoor Air" and "Determination of Total Volatile Organic Compounds (TVOC) in Indoor Air".

Chromatographic thermal desorption analyzer JX-4 semi-automatic dual channel primary thermal analyzerProduct Features:

1. Direct injection. Strong compatibility, suitable for gas chromatographs of various brands both domestically and internationally. Easy installation, no need to make any parameter or setting changes to the gas chromatograph, ensuring the consistency and integrity of the gas chromatograph.

2. The instrument adopts a microcontroller control system, integrates multiple controls, has a small size, compact structure, strong functions, and is expandable.

3. Adopting high-precision stabilizing valves and needle valves, with high stabilizing accuracy and stable airflow control.

4. Dual channel design allows for simultaneous analysis of two samples, reducing analysis time and achieving twice the result with half the effort.

5. All air ducts are made of 316 stainless steel that has been passivated and polished. The sealing rings are made of PTFE material, which is heat-resistant and non-volatile.

6. All heating air ducts use imported high inertia deactivated stainless steel air ducts, sealed with PTFE material, high temperature resistant, and non-volatile.

7. The heating valve box uses a precision high-temperature resistant six way valve with no dead volume, and the operating temperature can reach 240 ℃. The six way valve is driven by a motor and does not require external driving gas, making it easy to use.

8. The integrated design of heating valve box and heating gas path reduces intermediate links and lowers the problem of low resolution caused by dead volume.

9. By calculating the diameter of the analytical tube and gas path, a variable diameter joint was designed to reduce the dead volume at the connection point of the analytical tube and gas path.

10. Integrating three functions of standard sample simulation sampling, thermal analysis, and analytical tube activation, it has comprehensive functions and is economically practical.
