Nitrogen Sources and Uses

Nitrogen is one of the most common elements found in any living things along with carbon, hydroxide and oxygen. It is a colorless, odorless and tasteless atomic gas. But this can occur in any forms as liquid or solid when added to compounds like cyanide and ammonia.


Nitrogen is also called Mephitic Air according to Antoine Lavoiser, the father of Nutrition. However, Daniel Rutherford who discovered nitrogen described and named the element, Fixed Air.

Nitrogen is a very abundant gas. In fact, it can be found even in the human body in the form of amino acids. They are also component of the neurotransmitters of all living animals including humans. Hence, the human body alone contains more or lessĀ  three (3) per cent weight of nitrogen.

In the environment, there are many sources of nitrogen such as fertilizers in the form of nitrites and nitrates. They are usually produced by bacteria in the soil.

However, nitrogen can also be manufactured and produced by industries through the process of fractional distillation of liquid air. Another method of industrial process in production of nitrogen is by the use of gaseous nitrogen air.

Nitrogen is very useful in almost everywhere. In food production, it is used as an artificial modified atmosphere to help prevent fast oxidation processes and damages of the food. Nitrogen is also used in production of stainless steel as a shield gas. In cars and automobile industries, nitrogen is used to prevent tire combustion and even help prolong the life and usage of tires.

With the vast uses and applications of nitrogen gas, it is recommended to store nitrogen in the most appropriate compressed gas cylinder even just those small nitrogen cylinder for small-scale uses of the gas. In addition, small nitrogen cylinders are common cylinders used for nitrogen as an alternative to argon cylinders in manufacturing ordinary incandescent light bulbs.
