· A purge gas is a dry, clean gas that is directed through the purge gas pathway of Perma Pure dryers, countercurrent to the flow of the sample gas through the Nafion™ tubing. It is important that the purge gas is drier than the sample gas: when the partial pressure of water vapor in the purge gas is less than the sample gas, Nafion™ polymer …

· Group14 Technologies, a global provider of silicon-carbon composite materials for lithium-ion markets, and SK materials, one of the world’s top manufacturers of special gases and industrial gases, are forming a joint venture to build a factory for lithium-silicon battery materials in South Korea.. The joint venture is the latest development for Group14 to secure dual …

· Selected copper tube must be of suitable wall thickness for higher operation pressures. Use a tubing cutter, do not use a saw to cut pipe. De-bur and clean all cuts before assembly; Brazing: While brazing refrigerant pipes, flush them with nitrogen gas. Use a pressure regulator to maintain a flow rate of 1.76 ft3/h (0.05 m3/h) or more.

· A 100 per cent renewable way to make ammonia. Ammonia has sustained humanity since the early 20th century, but its production leaves a huge carbon footprint. Now researchers have found a way to make it 100 per cent renewable. Chemical engineers at UNSW Sydney and University of Sydney have found a way to make ‘green’ ammonia from air, water …

What is gas chromatography? Gas chromatography (GC) in analytical chemistry is a common type of chromatography where the mobile phase is a gas and the stationary phase is separated as a vapour. The mobile phase which we usually used in gas chromatography is noble gas or an unreactive gas such as helium, argon, nitrogen, and hydrogen.A sample is injected into a …

· Intangles’ ML-based fuel and AdBlue tracking algorithms can detect the exact amount and location of fillings/pilferages and in turn help compute accurate cost per …

· Connect soap film flow meter to the detector port outlet with the help of Teflon or rubber tube. Fill the pipette bulb partially with a soap solution and attach to the bottom of the flow meter. Open the knob of carrier gas (N2) and set up proper pressure (i.e. 500 kpa or 5 Kg/cm2) in carrier gas pressure controller.

· The Opening Lines. Use action-initiating opening lines when making the first move. You want a potential date to stick around for a convo. So, make them do it. Otherwise, you might never get your …
