Argon (4N)

Argon is one of the most common carrier gases in gas chromatography. Argon is used as a carrier gas in sputtering, plasma etching and ion implantations, and as a blanket atmosphere in crystalgrowth.*Due to market variability and unique gas requirements, we may not be able to provide a fixed pricelist. We warmly invite you to share your gas quantity and packaging requirements, enabling us to tailor a quote for you.

Process

The most common source of argon is an air separation plant. Air contains approx. 0.93% (vol.) argon. A crude argon stream containing up to 5% oxygen is removed from the main air separation column via a secondary (“side-arm”) column. The crude argon is then further purified to produce the various commercial grades required. Argon may also be recovered from the exhaust stream of certain ammonia plants.
   
Gas Argon
CAS No. 7440-37-1
Purity ≥99.99%
Purpose Used for inflating light bulbs and arc welding of stainless steel, magnesium, aluminum, etc., also known as “argon arc welding”. Pure argon is mainly used for metal welding, smelting, etc. High purity argon is mainly used in the semiconductor industry, smelting of rare and non-ferrous metals, protective gas in welding, filling gas for special light bulbs, and gas chromatography analyze the carrier gas and prepare the base gas for standard gas.
Emergency situation pressurized gas inside: may explode when exposed to heat
GHS hazard category pressurized gas
Physical and chemical hazards non combustible, no special explosive characteristics.

Applications

Electrical Welding

One of the most common application of argon, either pure or in various mixtures, is as a shielding gas for arc welding.

Glass

Argon is used as an insulation gas in high-efficiency multi-pane windows to improve thermal insulation.

Steel

Argon is also used in the iron and steel industry to prevent oxidation of molten metals and alloys and for degassing and desulphurization of molten steel and iron baths.

Medical

The pharmaceutical industry uses argon to displace oxygen in the top of intravenous drug containers, extending product shelf-life. Liquid argon is used in cryosurgery e.g., cryoablation to destroy cancer cells.

Wines

Argon is used for wine preservation to eliminate air by the heavier argon, to prevent oxidation and extend the product quality for opened bottles and barrels.

Metal Treating

Argon is used, often in a mixture with hydrogen, as a protective atmosphere for the heat treatment of certain metals, particularly those which are susceptible to nitriding when treated in a nitrogen-based atmosphere. This includes stainless steels and many different specialized and there-fore small-scale applications.

Frequently Asked Question

What is the purity of your argon gas? Which industries do you generally supply to?

We provide high-purity argon gas, with the highest purity reaching 6N (99.9999%). Our customers are in industries such as electronic semiconductors, medical, and research, requiring stable and continuous supply with a high volume of gas demand.

What is the minimum order quantity (MOQ) for your argon gas?

Our argon typically has an MOQ of around 100 cylinders. Single cylinder sales are not accepted.

Can your argon gas be used in welding and metal processing industries?

Certainly. Generally, high-purity gases can be suitable for industries with lower purity requirements, and the purity needed for welding and metal processing industries is not extremely high. However, there is a significant cost difference between high-purity and lower-purity gases, and cost is a crucial factor when choosing the gas that best fits one’s needs.

Can you provide liquid argon?

Certainly. However, due to the extremely low boiling point of liquid argon, which is -195.8 degrees Celsius (-320.4 degrees Fahrenheit), additional considerations for evaporation need to be taken into account during long-distance transportation.

Can you provide cylinders/dewars/tanks/tube trailers for argon gas?

We are a specialized gas supplier, and gases are our primary products. Generally, we can supply argon in cylinders or dewars along with the argon itself. We also accept customers’ tanks or tube trailers for filling at our facility but do not sell any tanks or tube trailers.
