Gas chromatography is mainly composed of the following parts: Carrier gas in a high-pressure cylinder with attendant pressure regulators and flow meters Helium, N2, H, Argon are used as carrier gases. Helium is preferred for thermal conductivity detectors because of its high thermal conductivity rel...
In the simulation test device, a nitrogen cylinder is used to fill high-purity nitrogen into the oil pipe to manufacture natural gas, and water is set outside the casing to cram into the annulus to affect the annular protection fluid. Plugs are formed at both ends of the pipe string ...
HF membrane modules can be fabricated by HF membrane bundles consisting of a large number of HF membranes and are normally in form of HF flat plate membrane modules and in cylinder modules. High productivity is achieved because of its high packing density and large surface area and also HF ...

The carrier gas (air) was combined with the target gas from a cylinder and maintained at a fixed concentration of 50 ppm. This gas mixture was subsequently directed through a programmable mass-flow controller (MFC; F-201CB Mass-flow Controller, Bronkhorst, Ruurlo, The Netherlands). The target...
