2、 Explanation

The improved U-shaped adsorption tube of our company is easy to operate, has good quantitative repeatability, high analytical accuracy, and has been proven by practical experience for a large number of users. The sampling resistance meets the requirements specified in the new standard: when the flow rate is 0.5L/min, the resistance should be between 5Kpa and 10Kpa.

Our company has successfully developed a benzene specific modified activated carbon adsorption tube, which has a good peak shape for benzene and high analysis accuracy.

The thermal desorption devices produced by our company are equipped with the functions of constant temperature of the injection valve and output pipeline at 100-150 ° C, ensuring the long-term stability and quantitative analysis accuracy of the instrument.

Existing instruments of our company's users can be modified according to the new standard requirements.
