Oxygen (O2)
Oxygen is a colorless, odorless reactive gas and the life-supporting component of air. It forms just under 21% of the Earth’s atmosphere and is the most abundant element in the Earth’s crust, mainly in the form of oxides, silicates, and carbonates.
In addition to its use as a respiratory gas for healthcare applications, oxygen has strong oxidizing properties that can benefit many industries by improving yields, optimizing performance, lowering costs, and reducing carbon footprint compared to other fuels. Oxygen enrichment or replacement of air also enhances chemical and biological process efficiency.
Application of Oxygen:
- Steel Manufacturing
- Chemical Processing
- Pulp and Paper

Argon (Ar)
Argon is one of the Noble gases. It is a colourless and odourless gas which is inert to other substances. Argon finds diverse applications across various industries, with its primary use as a shielding gas in arc welding, either in its pure form or as part of different mixtures. Additionally, it is a key component in the filling mixtures for incandescent lamps, phosphorescent tubes, and thyratron radio tubes.
In the iron, steel, and heat treatment industries, Argon plays a vital protective role, especially for metals prone to nitriding when exposed to a nitrogen-based atmosphere.
Argon serves as a carrier gas in various applications such as chromatography, sputtering, plasma etching, and ion implantations. It plays a crucial role in creating a protective atmosphere in crystal growth, viniculture, and pharmaceutical packaging. In the case of excimer lasers, argon is combined with fluorine and helium.

Helium (He)
Helium (He) is a gas characterized by its colorless, odorless, non-toxic, non-corrosive, and non-combustible properties. Primarily extracted from natural gas wells, this precious gas is globally scarce, prompting the integration of recovery and recycling systems in various applications.
With the lowest boiling point of any gas (4.2 Kelvin or –269° Celsius), liquid helium is the coldest matter on Earth. This makes it ideal as a cryogenic agent for several cutting-edge medical and physics applications. For instance, it is used to cool superconductive magnetic coils in magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) medical equipment.
Indeed, helium plays an essential role in numerous industries. Its applications include pressurizing rocket fuel, establishing inert atmospheres for welding, heat treatment, and epitaxial crystal growth, purging semiconductor atmospheres, calibrating analytical instruments, inflating airplane tires and airbags, testing for leaks, inflating large balloons for meteorological studies, and filling electronic tubes in neon signs.
Depending on your volume requirements, we can supply helium in special insulated ISO containers, tube trailers, dewars, multi-cylinder packs (MCPs), regular cylinders, or portable cylinders.
Hydrogen (H2)
Hydrogen (H2) is a gas without odor, color, or taste, generated through either natural gas steam reforming or water electrolysis. Being lighter than air, it produces a clean and invisible flame without carbon or soot. Notably, hydrogen is the sole fuel gas devoid of carbon atoms. It boasts the highest thermal conductivity among all gases. When combined with oxygen, the hydrogen flame achieves a temperature of 2834°C.
It is often mixed with argon to create a range of argon/hydrogen shielding gases for TIG and plasma welding. These shielding gas mixtures are primarily used for welding austenitic stainless steels and some nickel alloys. Hydrogen can also be used with argon in a range of gas mixtures for plasma-cutting (stainless steel and aluminum mainly).
Hydrogen extends its utility far beyond being a fuel gas, finding diverse applications in the manufacturing of carbon steels, special metals, and semiconductors. Within the electronics sector, it serves as a prevalent reducing agent and carrier gas. Additionally, high-purity hydrogen plays a crucial role as a carrier gas in gas chromatography.
In addition, it can be combined with oxygen for underwater flame-cutting. Deeper cutting applications require higher fuel and oxygen pressures. Hydrogen is ideal here as it is supplied at higher pressures than other fuel gases. In the glass industry, hydrogen is used to form the rim on glasses.
Nitrogen (N2)
Nitrogen serves various essential functions across industries, particularly in the food and chemical sectors, where it is utilized for blanketing, purging, and sparging. Additionally, it plays a crucial role in modified atmosphere packaging (MAP) for food products. In its liquid state, nitrogen proves valuable for shock-freezing food, storing biological materials, conducting cryosurgery, and cryogenically processing plastics and rubbers.
The semiconductor industry relies heavily on nitrogen, employing it as both a purge and carrier gas. In electronics, it serves as an inerting agent for epitaxial reactors and functions as a carrier, zero, and balancing gas in laboratory analyses. Nitrogen finds applications in diverse areas such as heat treatment, ammonia production, fire extinguishing in mines, tire filling, shrink-fitting, and cold traps, contributing to enhanced vacuum efficiency.
