Helium purity
WebUltra high purity helium is also commonly used in mass spectrometry, which is an analytical technique that measures the mass-to-charge ratio of ions - or in other words, leak detection. Helium is the best choice for this task for the same reasons that it’s an excellent choice for many other uses: it’s inert, non-toxic, non-condensable, and non-flammable. WebBuy Helium Gas or Purchase Liquid Helium (He) Helium is a highly specialized product. It’s chemically inert and non-flammable, with high thermal conductivity, low molecular weight and size, and the lowest boiling point known. We deliver gas and liquid helium (He) in a variety of purities up to 99.999%.

WebHelium (He), nitrogen (N 2 ), hydrogen (H 2 ), and argon (Ar) are often used. Helium and nitrogen are most commonly used and the use of helium is desirable when using a … WebFor example, helium must meet the requirement of 99.999% purity for use as the carrier gas in an Agilent GC system. This means that the concentration of impurities should not exceed 10 ppm. Therefore, it is critical to detect ppm level impurities in helium. This application brief demonstrates the analysis of impurities in helium, on

The inert properties and the high diffusion capacity makes pure helium an excellent carrier gas in gas chromatography. Webthe heat exchangers of a helium-cooled reactor require knowledge of some of the thermophysical properties of the helium gas, and the same applies to the treatment of observed data in heat transfer experiments. The properties treated in this report are the density, the specific heats, the thermal conductivity, and the viscosity.
Webreservoir presence and gas charge and a working helium system, to differing degrees within each prospect. Several wells tested non-flammable gas, the only two analysed for helium confirmed helium presence; and • 20 miles south of and connected by pipeline to the operational Lisbon Helium Plant (99.9995% purity). WebThe influence of atmospheric pressure is minimal and can be ignored under normobaric conditions. At 0 degrees Celsius, the speed of sound is about 970 meters per second in pure helium, 330 meters per second in air, and 315 meters per second in pure oxygen. If the temperature is increased by 1 degree, the speed of sound increases by about 0.175%.
WebMulti-functionality. Every analyzer has built in calculator for mixing gases. As well as a continuous mixing mode, for watching the oxygen and helium concentration with warning alarms, when the mixture falls out of preset limits. The professional model can also function as an emergency compressor shut off (after connecting a relay).
