High purity gases are specifically designed to be used in analytical activities. With the lowest level of impurities that are available in the market, these gases provide consistent and reliable operations and analytical results. Typical applications are calibration of instruments, material testing and research.

• High purity nitrogen: used in secondary steel refining, casting heat treatment, lamp industries, food packaging, optical fibers etc.
• High purity argon: used as carrier gas for gas chromatographs, microelectronics, etc

Any specific gas mixtures of desired purity can also be provided by Green ASU based on your requirements.
