The HP2 helium purifier provides “point-of-use” purification of helium or other noble gases to sub-ppm levels. The NP2 (nitrogen purifier) purifies nitrogen to sub-ppm levels. The substrate in these purifiers is a non-evaporable gettering alloy. This stable alloy is contained in a welded assembly, so the purifiers can be used safely in industrial applications with minimal precautions. A self-regulating design eliminates the possibility of thermal runaway and maintains the getter material at the optimum temperature.
