Irreversibly removes contaminants from carrier gas. Use this purifier for point-of-use gas polishing and final visual quality assurance before gas enters the GC. Simultaneously removes oxygen, water vapor, carbon monoxide, carbon dioxide, most sulfur compounds, most halogen compounds, alcohols, and phenols to less than 10ppb. Install the OMI tube downstream from your primary gas purifying device, and tell at a glance whether or not oxygen and moisture are being effectively eliminated from your system. The tube contains Nanochem resin, developed for the demanding gas purity needs of the semiconductor manufacturing industry. As little as 1ppm of oxygen or moisture will change the indicating resin from black to brown. Spent tubes are easily replaced. Simply unscrew the end assembly from the tube holder and replace your OMI tube. The design prevents air from entering the new tube during installation.
