Pure Gases

Trace Analytics, LLC provides analyses for pure gases used in a variety of industries. Testing can include gas purity by difference e.g. the pure gas concentration is determined to ± 0.3% absolute, then all other determined gases are subtracted from 100.00% to arrive at the reported value.

We provide Gas Purity Testing for the following gases:

  • Argon
  • Nitrogen
  • Nitrous Oxide
  • Oxygen

Impurity Testing – Inert Gases

Impurities such as oxygen, nitrogen, carbon monoxide, carbon dioxide, total volatile hydrocarbons, halogenated hydrocarbons, and water can be determined for the above pure gases. We can also provide analyses of particles, water, and oil for pure gas systems.

The following are gas specifications commonly used. We can also provide a custom specification based on your requirements.
