The experimental results demonstrated that certain gaseous mixtures, and even some pure gases, under well-defined and specific operating conditions, are more efficient in selected heat transfer applications than pure helium alone. The cost savings that may be a result of diluting helium with another ...
pure gaseous helium, cooling/liquefying method for superconducting system, involves compressing gas along compression stages, where stages are realized by machine and flow of gas is higher than specific value The method involves compressing working gas e.g. pure gaseous helium, in a compression ...

The BTEX chemical analyses were performed by GC-MS on a Varian 450GC 220MS chromatograph using a VF-5MS column (30 m, 0.25 mm, and 0.25 μm). Injections of 1.0 μL of sample were conducted at 200 °C, with a split ratio of 1:4, using helium 5.0 as carrier gas at 2.0 mL min...
The carbon monoxide may be used as a pure gas or may be used with diluting by an inert gas (for example, nitrogen, helium, and carbon dioxide). The partial pressure of carbon monoxide in the reaction system may be selected suitably according to the type or mode of reaction, etc. For ...
