What distinguishes helium from helium grade A grade B

Feature

Helium can be described as the monatomic inert gas. It is very difficult to obtain solid or liquid form of helium, so the most of its compounds exist in the gas form and is extremely unstable.

For example, there are two forms of helium, and mark B. Marcia from Each other they differ by the purity of the gas. We can say that helium grade A – this is first grade, and the grade B helium is the second . Helium grade And produced to higher requirements, so the volume fraction is pure helium is 99.995%. In the case of the brand this number below to 99.99%.

The helium gas mark And is composed of impurities of nitrogen, hydrogen, oxygen, neon, and argon 0.005% and 0.01%. Such a small number can be removed from the helium, i.e. it can be frozen on the working surface without affecting processes or cleaned their own treatment systems.

The same can be said about the brand, however, it is worth considering that the proportion of substances, for example, nitrogen, hydrocarbons and neon, more than in the case of brand And that narrows the scope of use of such helium.

Application

The scope of grade A helium is much broader than brand B. the Oxygen contained in the air, does not allow for chemical reactions with the required frequency. To the desired substance is not in contact with the gases of the air, it is important to create certain conditions that helps make it a grade A helium in cylinders. It is widely used as an inert environment in order to carry out welding works with tradeplace metals. In addition, this component can be environmental in organic synthesis. Helium can be used in medicine, as in combination with oxygen it removes the attacks in asthmatics.

The inert gas is almost insoluble in water, so it is used when working at depth. Helium grade a saves divers from decompression. It is also used in the food industry as an additional element of conservation that helps the products do not lose the original flavor and taste.

Scope of grade B helium is not so extensive. Its main use is as a balloon filler. It is a subsidiary element of the decor, because it is able to transform any room and create a festive extravaganza under the open sky. This form allows helium to decorate the celebration. Although helium grade a and grade B helium is different from each other, each of them has properties that can be used in various fields of everyday life.
