Inert gases are a group of elements that are chemically inactive and have very low reactivity with other elements. This makes them useful in a variety of industrial and laboratory applications. Two types of inert gases that are commonly used are industrial-grade inert gases and laboratory-grade inert gases. This article will explore the benefits of using these types, like argon gas, helium etc., in different settings.
Industrial Grade Inert Gases
Industrial-grade inert gases are commonly used in industrial processes where their lack of reactivity is highly valued. These gases are often used in welding, heat treating, and metal fabrication applications. Argon, helium, and nitrogen are industrial-grade inert gases most commonly used.
Welding
Argon and helium are commonly used as welding gases because they protect the weld from oxidation and other contaminants. Welding with inert gas is known as gas tungsten arc welding (GTAW) or inert tungsten gas (TIG) welding. These types of welding produce high-quality welds that are strong, clean, and free from defects.
Heat Treating
Industrial-grade inert gases are also used in heat-treating applications. Heat treating is a process of heating and cooling metals to alter their physical and mechanical properties. This can make them stiffer, more malleable, or more corrosion-resistant. Using inert gases during heat treatment prevents oxidation and contamination, producing a high-quality finished product.
Metal Fabrication
Another common use of inert gases is in metal fabrication. Metal fabrication involves cutting, bending, and shaping metal to produce a finished product. Using inert gases during these processes prevents oxidation and other forms of contamination, ensuring that the finished product is of high quality.
Laboratory Grade Inert Gases
Laboratory-grade inert gases are commonly used in laboratory settings for various applications. The most commonly used laboratory-grade inert gases are helium, neon, argon gas, krypton, and xenon.
Chromatography
One of the most common applications of inert gases is chromatography. Chromatography is a process used to separate and analyse mixtures of substances. Using inert gases during this process prevents chemical reactions that could alter the analysis results. Helium is the most commonly used inert gas for gas chromatography.
Benefits of Industrial and Laboratory Grade Inert Gases
The use of industrial and laboratory-grade inert gases offers a variety of benefits, including:
Improved Quality of Finished Products
Using inert gases during industrial processes and laboratory applications ensures the finished product is of high quality. Inert gases prevent oxidation and other forms of contamination, which can weaken or alter the properties of the finished product.
Increased Safety
Inert gases are non-toxic, non-flammable, and non-reactive, making them safe to use in various settings. Using inert gases in welding, for example, prevents the formation of toxic fumes and vapours that could harm workers.
Versatility
Industrial and laboratory-grade inert gases are versatile and can be used in various applications. This makes them a valuable tool for many industries, from manufacturing to pharmaceuticals.
Environmentally Friendly
Inert gases are environmentally friendly and do not contribute to air pollution or climate change. They can be safely released into the atmosphere without causing harm.
Summing Up
In conclusion, the benefits of industrial and laboratory-grade inert gases are numerous. Using inert gases offers various advantages, from improved quality of finished products to increased safety and cost-effectiveness. In the manufacturing industry or laboratory settings, inert gases are essential in ensuring that processes are safe, efficient, and high-quality.
