High Purity Gases Supplier

What are specialty or high-purity gases?

We produce and supply specialty gases, which are extensively used in laboratory analysis and industrial applications. Specialty or high-purity gases (mixtures) are products that have met all the requirements of component purity and impurity content, are manufactured as per specific technology, and are used in tiny amounts for scientific, technological and analytical (metrological) purposes. Also, they satisfy most requirements related to diffusive resistance, hermiticity and reactivity. High-purity gases manufactured by top-notch companies include high-purity calibration gas mixtures, liquid gases, cylinder gases, mixtures for medical tools sterilisation and laser mixtures.

We select a suitable specialty gas, proper gas packaging and delivery system, and optimise the process with our high-purity gas specialists to review the operations and deliver products manufactured and approved by qualified laboratory technicians who use advanced analytical technology to meet the customer specifications. High-purity gases include argon, air, carbon dioxide, helium, hydrogen, oxygen, nitrogen, hydrocarbons, rare gases, customised gas mixtures and EPA protocol gases.

Where are high-purity gases used?

We manufacture and package our high-quality gases by checking raw material quality with analytical methods such as atomic emission spectrometry, chromatography atomic absorption and more. We ecologically monitor the highly toxic and explosive substances in the atmosphere while maintaining an inert, protective and reducing atmosphere. They further aid in the production of UHP gases. Manufacturing companies also work with high-purity gases, which help research, laser technology, clinical diagnosis and chemical synthesis.

High-purity gases are commonly used in analytical activities as they provide reliable and consistent results. They work with the lowest level of impurities available, and general applications consist of the calibration of research, material testing and instrument. High-purity nitrogen is popularly used in casting heat treatment, food packaging, secondary steel refining, lamp industries and optical fibres. High-purity hydrogen and helium are used in gas chromatographs, while high-purity argon is used as the carrier gas for microelectronics and gas chromatographs.

We offer a complete range of specialty high-purity gases!

As we have worked with gases for multiple decades, we know that each gas comes with a purpose. From argon to xenon, we offer all kinds of pure gases: noble gases (helium, krypton, neon, and xenon), air gases (argon, nitrogen, and oxygen), hydrogen, carbon dioxide, hydrocarbons, and carbon monoxide. We also have inorganic gases (ammonia, sulphur dioxide, and chlorine) and organic gases (acetylene, ethylene, ethane, propane, propylene, butane, hexane, and methane).

Our products are manufactured and packaged while adhering to stringent product quality standards. We use advanced analytical equipment that complies with global regulations, is managed by qualified and experienced laboratory technicians, and carefully sourced raw materials. In addition, we have provided the proper training to our sales team, so that they understand your requirement, suggest the correct products and packaging to ensure industry specifications and customer expectations.

You can trust our products!

We manufacture our products with the utmost consideration for stringent quality standards, starting from the raw materials, production stages, and compliance with government regulations. Our company follows all quality guidelines as set by the highest authority of India and adhere to the control measurements and individual cylinder analysis, which determines the gas quality requirement. In addition, we use several applications, specifications, and instruments to measure gas purity and removing impurities.

We have different grading systems to measure UHP gas purity. Our products are available across all shapes and sizes, right from bulk supply down to tiny cylinders. We understand that different companies have specific sets of requirements, which is why we’re happy to take customized orders.

Our experts would be happy to select the right product, package, and deliver high-purity gases for your requirements. All you have to do is to book an appointment with us.
