For

Trace Gas Impurities Gas Chromatography System

26 January 2026

1. Background:

The Aerospace Fuels Laboratory at Vandenberg Space Force Base (AFPET/PTPLE) provides laboratory quality surveillance and investigative analytical support of flight critical products directly related to the warfighter and space launch operations on behalf of all Air Force and other DoD agencies, as well as commercial entities. AFPET/PTPLE has a vision to create a flexible, dynamic center of excellence that is responsive to customers and strategically positioned and focused to contingency and warfighter operations. We provide the warfighter and space launch activities with specialized testing services and capabilities in petroleum, propellants, cryogenics, chemicals and gases for all aerospace vehicles, systems, and equipment.

2. Scope:

AFPET/PTPLE has a requirement for one Gas Chromatography System to perform quantification of trace permanent gas impurities in Propellant-Grade Nitrogen, Helium, and Hydrogen. This GC system will be used to satisfy specification testing requirements for MIL-PRF-27401H (Nitrogen), MIL-PRF-27407E (Helium) and MIL-PRF-27201 (Hydrogen). This will need to be a robust unit for routine specification and/or investigative testing.
