The PTFE hydrogen chloride sampling filter membrane clamp is produced and provided by Shanghai Shupei Experimental Equipment Co., Ltd. The product specifications are complete. The filter membrane clamp is generally used for hydrogen chloride sampling in the environmental testing HJ549-2016 standard. During sampling, the filter membrane is clamped in the filter membrane clamp, connected in series with two impact absorption bottles and connected to the air sampler.

Product Introduction:

Specifications: 25mm, 40mm, 47mm (used in conjunction with filter membrane)

Color: Milky white

Usage: Used for HJ549-2016 to replace HJ549-2009 for the determination of hydrogen chloride in ambient air and exhaust gas

Characteristics: Durable-200 ℃ to+250 ℃. Does not adhere to any substance, has no effect on experimental analysis, and is resistant to organic solvents such as strong acids and bases.

The distribution and sampling of ambient air should comply with the relevant provisions of HJ664 and HJ/T194. During sampling, clamp the filter membrane into the filter membrane clamp, and then connect two 25ml impact absorption bottles each containing 10ml of water as the absorption solution in series. Connect them to an air sampler and sample at a flow rate of 0.5L/min~1.0L/min for at least 45 minutes. The flow deviation before and after sampling should be ≤ 5%
