Ultra High Purity Gases
BSTG produces ultra-high purity gases of Nitrogen, Argon, Hydrogen, Helium, and Oxygen with 99.9999%, 99.9995%, and 99.999% purity respectively.
We accomplish these purities through several technically challenging processes and purification systems. In addition, these purities will be verified in our modern analytical testing laboratory accredited to ISO/IEC 17025:2017. These processes include cylinder preparation, filling process, proprietary purification technique to each gas, and analytical systems and methods designed to identify impurities less than parts per million (PPM).
