Main Applications

Suitable for environmental monitoring stations, 室内环境、第三方检测机构、科研机构、半导体、 新能源、生物医药及相关企业单位对于气体样品中挥发性有机化合物采 集分析方法等应用场景，也适用于美国 EPA TO15、TO14、PAMS 等挥发 性有机物样品采集和一定周期的存放，满足国标 HJ759-2015 、GB/T & nbsp;37185-2018 on sampling gas chromatography/mass spectrometry (GC/MS) method and the application requirements of the "2019 monitoring program of ambient air volatile organic compounds in prefecture-level and above cities".

Technical Parameters

Specification: 0.5L/1L/3L/6L/15L canisters can be selected according to the volume of sampling gas

Flow rate range: 0.12ml/min-400ml/min

Material: SUS316 Stainless Steel

Material: SUS316 Stainless Steel

Flow rate stability: 24h≤±1%

Extremely good inertia, for the more active sulfur-containing compounds to save 30 days analytical reproducibility of up to 99%

Inside of the analyzer, the analytical reproducibility is up to 99%. quot;>Internal wall treatment: advanced electropolishing tanks or Silonite tanks

Internal wall treatment: state-of-the-art electro-polishing tanks or silonite tanksMaximum pressure: 40psi

Using non-powered sampling, more suitable for field sampling

1 Ultra-high inertness surface treatment technology

2 Strong compatibility

CompatibleContains all the samplers, canister cleaning systems, distribution systems, and other equipment on the market. The system is designed to accommodate all samplers, tank cleaning systems, gas distribution systems and pre-concentrator handling systems available on the market, sampling tanks, tank cleaning systems, gas distribution systems and pre-concentrator handling systems. quot;>The sampling tank and valves are made of stainless steel, which is durable and can be used in harsh field environments.

3 Good air tightness<

< gt;To Nitrogen pressurized to 30psi, measure and record the initial pressure, then close the valve of the sampling tank, open the valve after 24h, test and record the pressure, the pressure in the tank should not be reduced more than 2psi after 24h. The pressure inside the tank should not decrease more than 2psi after 24h, and the vacuum pump can reach a vacuum level below 50mtorr.
