1、 Key parts

Equipped with blow protection valve: positive pressure protection/super seal/special material

PDHIDDetector: American award-winning product/PDPID, PDECD mode

Gas Purifier: PDHID specific/for 99.999% high-purity helium, purifying impurities ≤ 10ppb/long service life.

twoInstrument features:

① Provide a one-stop service for installation, debugging, and operation, with good reliability and long barrier free running time.

② There are two types of pneumatic control, manual and EPC, which are easy to use and have the function of network transmission, unmanned completion, statistical analysis and monitoring.

③ We have adopted VICI's original imported PDHID detector, which won the Analytical Instrument Award that year and has been widely promoted and applied over the years.

④ When analyzing samples containing sulfur-containing components, the instrument used is SilcoTek from the United States ® The silicon passivation treatment process ensures the accuracy of the analysis.

⑤ In order to prevent cross contamination between the sample and the atmosphere or the escape of toxic samples during injection, a special protective sleeve injection valve is used.

⑥ The injection valve, switching valve, and gas system used in the instrument are all imported from VICI company.

⑦ In order to obtain the optimal minimum detection amount, the instrument thoroughly and targetedly purified the carrier gas high-purity helium, using an HP2 gas purifier.
