NASA's Johnson Space Center employs ultra-high purity (UHP) nitrogen to safeguard moon rocks collected over half a century of space missions. These invaluable artifacts are kept in sealed glove boxes that mimic the lunar environment.

Ensuring the purity of UHP nitrogen is essential, which is why NASA and Jacobs Engineering collaborate with the Analytical Science and Technologies Group (ASTG).

ASTG was asked to design, construct, deliver, and commission a comprehensive monitoring solution tailored explicitly for trace-level (ppt/ppb) gas analysis requirements.

Thanks to over two decades of experience, ASTG has positioned itself as a valued provider of precise gas monitoring systems across various industries, including semiconductors, beverage carbon dioxide (CO2), pharmaceutical, medical, and aerospace.

The system developed for NASA and Jacobs Engineering incorporates advanced technologies capable of measuring trace levels of water, argon, methane, oxygen, and non-methane hydrocarbons.

This significant project highlights ASTG's expertise, meticulous attention to detail, and track record in delivering high-quality solutions for critical applications.
