Your Air gas specialty gas representative can help you decide which option is best for your operation. Be sure to ask about our unique line of specialty gas equipment, including automatic changeover systems for
Nitrogen, hydrogen, and helium are the most widely used gases by today’s chromatographer. Each has unique benefits as well as drawbacks. Nitrogen shows the best efficiency, but over a low and narrow linear velocity range. Therefore, it is extremely slow as a carrier gas, and not a great choice for temperature-programmed use.
Off-the-shelf and custom designed helium refrigerators used in applications including gas phase, supercritical and liquid across a temperature range from 80K to 3K. A helium refrigerator is a closed cycle process system where warm pure helium gas enters the system and is refrigerated to produce a pure, liquid helium or cold helium vapor product ...
The temperature required to produce liquid helium is low because of the weakness of the attractions between the helium atoms. These interatomic forces in helium are weak to begin with because helium is a noble gas, but the interatomic attractions are reduced even more by …
Since the helium shortage of 2012/13 a number of GC methods that were previously restricted to helium carrier gas have been revalidated for use with hydrogen and nitrogen, giving labs the option to use cheaper alternatives to helium that are also available from gas generators.
Helium is one of the basic chemical elements. In its natural state, helium is a colorless gas known for its low density and low chemical reactivity. It is probably best known as a non-flammable substitute for hydrogen to provide the lift in blimps and balloons.
time of analysis and the efficiency of the chromatography. Helium carrier gas is near optimum linear velocity at 25 cm/sec. as shown in the first figure. The analysis time is approximately 14 minutes and the % coating efficiency (CE) is 86%. When we double the helium carrier gas velocity to 50 cm/sec. we
· Modern Uses: Today, helium gas is used in a wide range of industrial, commercial and recreational applications. The most well-known is perhaps flight, where helium gas (being lighter than air ...
Helium is a unique product. It has very low boiling point (?268.94 °С), high thermal conductivity and electric conductivity. Thanks to its properties, helium is widely used in a range of industries, such as aviation, aerospace, electronics, nuclear power, and healthcare.
The resulting crude helium gas is purified by successive exposures to lowering temperatures, in which almost all of the remaining nitrogen and other gases are precipitated out of the gaseous mixture. Activated charcoal is used as a final purification step, usually resulting in 99.995% pure Grade-A helium.
Available in a range of functions, the gas mass flowmeter employs a unique method of measuring gas flow rate that is also resistant to changes in temperature and pressure. To obtain stable measurement, a conventional flowmeter requires a long straight piping area at the upstream side. The gas mass flowmeter, however, can assure stable measurement
of Helium”, with the aim to become a convenient, alternative source of the in-demand gas for US customers. The Holbrook Basin has several of . the world’s richest producing helium gas fields, including the Pinta Dome and the Navajo Springs. Concentrations of helium gas range up to 8% to 10%, compared to the industry benchmark of 0.3% to 1%.
Hydrogen is the most efficient lifting gas. Its lift is about 8% better than helium. Hydrogen is a diatomic molecule whereas helium is monatomic. So, hydrogen leaks more slowly than helium due to its larger molecular size. Hydrogen is flammable in a wide range of mixtures with air; although, it has a high ignition temperature.

The Effect of Helium on Airship Range and Payload. In actual use, because of physical realities and operational considerations, the use of helium can reduce an airship’s payload lift by almost half. Fixed Weight vs. Lifting Gas
Our bulk liquid and gas delivery systems allow us to provide a full range of purities to meet your helium supply needs. We offer gaseous helium in tube trailers, in receivers permanently installed onsite, or in ISO framed modules.
In a light-gas gun, the piston is powered by a chemical reaction (usually gunpowder), and the working fluid is a lighter gas, such as helium or hydrogen (though helium is much safer to work with, hydrogen offers the best performance [as explained below] and causes less launch-tube erosion). One addition that a light-gas gun adds to the airgun ...
We offer helium in high-pressure gas cylinders and liquid dewars—available in a variety of sizes—to meet any and all low-volume needs. Bulk Deliveries Helium is also available in bulk gas and liquid delivery, as well as in a full range of purities and tank sizes. Inventory Management
