Automatic secondary thermal analyzer

KJZ-300 typeAutomatic secondary thermal analyzerIntroduction

The KJZ-300 automatic secondary thermal desorption instrument is a replacement product independently developed and launched by Kejie Group, directly targeting domestic and foreign users. This instrument is suitable for qualitative and quantitative detection of various gases with boiling points below 350 ℃ in chemical building materials, food safety, atmospheric and indoor environments. It can be connected to any domestic or foreign gas chromatograph or gas chromatography-mass spectrometry instrument, and its repeatability, sensitivity and other indicators can meet the requirements of the current national environmental detection standards. It also has its own functional advantages and satisfactory performance and price ratio in structure. Fully automated design, touch screen display, and more convenient operation.

KJZ-300 typeAutomatic secondary thermal analyzerPerformance Characteristics

1. Adopting semiconductor refrigeration to save usage costs, electronic refrigeration and second-order thermal desorption process to ensure narrow chromatographic peak shapes;

2. All sample transmission pipelines adopt imported high inertia deactivation pipelines, with no residue or cross contamination, ensuring the repeatability and accuracy of sample injection;

3. Software program control, with main functions including:

(1) After setting the method parameters, real-time animation can be used to display the working status and running time

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

(3) Set up the analysis program and press the run button to automatically complete the sample analysis

(4) It can be configured as a room temperature secondary desorption instrument or a low-temperature secondary desorption instrument according to user needs

(5) 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. Adopting a high-temperature six way valve, the operating temperature can reach 240 ° C

6. Through time programming, automatic functions such as desorption, blowdown adsorption and desorption, injection, and backwash cleaning can be achieved

7. Adopting 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 match imported gas chromatographs of various brands and ensure more convenient use and accurate data, this instrument is also equipped with dedicated interfaces for various imported instruments, which are easy to connect: 10. The connection point between the six way valve and the transmission pipeline is located in the heating and insulation box, without transmission cold spots, ensuring the integrity of the sample

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

12. Integrated design, compact overall structure; Microcomputer controlled 7-inch LCD display in Chinese, easy and convenient to operate

13. Secondary analysis heating rate>3000 ℃/min, peak width<3s
