Our priority is to attain the highest levels of purity, consistency, traceability, and stability of pure and specialty gases for academia and research. These gases as well as rare gases and custom prepared gas mixtures maintain strict quality control during production. When purity is essential, Cryo-Asia can supply in purities up to N6.0 (99.9999%).  These include acetylene, argon, helium, hydrogen, and nitrogen which are used for analytical instruments, as well as rare gases such as xenon, neon, and krypton.
