Helium gas is non-flammable, colorless and odorless and non-reactive. Inhalation of this gas in high concentrations causes suffocation. The density and density of helium is much lower than air, that is why it escapes to the upper layers of the atmosphere and small amounts of it can be found on the surface close to the ground. In general, you cannot find a significant percentage of helium in the whole atmosphere of the earth. Helium gas is used in pure form in laboratory purposes, and we will further discuss the uses of this unique gas.
Types of helium gas purity
Helium gas is supplied with different purities for different applications.
Grade 5 helium gas with 99.999% purity
Helium gas grade 5.5 with 99.9995% purity
Grade 6 helium gas with 99.9999% purity
They are among the most common types of helium purity available in the market and are used for various purposes. They use the purest grade of helium for precise laboratory purposes.
Helium is the smallest member of the group of noble gases with chemical symbol He and atomic number 2. This element has monoatomic molecules at standard temperature and pressure and exists in a gaseous state. Helium gas has an atomic mass of about 4 g/mol. This gas is colorless, odorless and tasteless. It is not toxic and is considered a neutral gas. This means that it does not undergo any chemical reaction in the standard state and does not have a known combination with other elements. The melting temperature of helium is very low compared to other elements, and its low temperature in liquid state has defined very special applications for it.
Helium gas is one of the most ineffective gases. This gas has various uses, some of which will be mentioned below. Helium is used in space and rocket industries. Helium is widely used in the welding industry as an indirect shielding gas for arc welding. They also use it for advanced leak detection testing. A gas mixture of helium and oxygen in different concentrations is used as breathing gas for divers who work at great depth and breathing gas for acute zinc patients. Helium is used to fill large balloons for space studies, as well as small balloons to carry weather forecasts and recreational balloons.
A mixture of helium gas with hydrocarbons is used for Geiger counters to detect X-rays. Helium is used as a carrier gas or as a pure gas for a variety of semiconductor processes. It is used as a balance gas or as a carrier gas in gas sampling. Helium is also used as a coolant and protector for drawing optical fiber. Helium is used as a balance gas in all types of lasers as a buffer gas or a carrier gas and to create an inert atmosphere for interwoven crystal growth. Liquid helium can be used to cool superconducting magnets in NMR spectrometers and medical MRI devices.This gas cannot be obtained from the earth's atmosphere and from the partial distillation of liquid air. Because there are small amounts of it in the earth's atmosphere. If it is known as the second most abundant element in the universe. The main source of helium is natural gas wells. This operation is performed by liquefaction. Due to the lack of helium in the world, all applications have recycling systems to minimize the wastage of helium.Zagros Air Liquid Company is an importer of high purity gas capsules.
