Performance characteristics

1 Ultra-high inert surface treatment technology

The inner wall adopts innovative ultra-high inert surface treatment technology (chemical vapor coating) and ultrasonic process. The tank has no adsorption to VOC, ensuring sample stability and recovery rate; ppb level sulfur, nitrogen compounds and polar (aldehydes, alcohols, esters, ketones, ethers, etc.) and non-polar compounds can also be easily and non-destructively collected and stored for a long period of time..

2 Strong compatibility

Compatible with all samplers, sampling tank cleaning systems, gas distribution systems and pre-concentrator processing systems on the market, The sampling tank and valve are made of stainless steel, which is durable and can adapt to harsh field use environments.

3 Good air tightness

withNitrogen is pressurized to 30psi, measure and record the initial pressure, then close the sampling tank valve, open the valve after 24 hours, test and record its pressure. The pressure in the tank should not drop by more than 2psi after 24 hours, and the vacuum pump can achieve a vacuum degree below 50mtorr.

4 Diaphragm valve

Diaphragm valve, lined with isolation diaphragm, no filler, maximum pressure resistance 250psig; temperature: 200℃, dead volume: <5µl, internal volume: 150ul; ultra-long and durable design to prevent damage to the slipping thread due to excessive force and affect the air tightness, effective sealing opening and closing times ≥15000 times.

5 Optional pressure gauge head
