Argon in the Atmosphere in St. Louis07/25/2019It is well known that the air on Earth is made up of multiple gases, oxygen and nitrogen being the two major gases. Yet Argon is another gas that although does not have as high of a concentration in the atmosphere, has shown itself to be just as important across multiple industries. Argon is an inert, monochrome and unscented gas that only inhabits approximately 1% of the Earth’s atmosphere. Although this gas is limited in quantity, it is consumed across multiple industries. In museums, Argon has traditionally been used for historic preservation. Historically meaningful documents, such as the Declaration of Independence and the Magna Carta, are conserved using Argon. Unlike Oxygen, Argon does not decay the paper or ink of these, especially delicate records. Argon is also used as a gas shield in the welding industry for arc welding. Considering the diverse use cases for this gas, there remains a continuous demand for the substance. Because of this, specialty gases like Argon are typically sold in smaller capacities and containers. PurityPlus carries only the purest of Argon and a variety of other specialty gases.
