About this file
This document is a specifications sheet for a NASA procurement of high-purity xenon gas for electric propulsion testing at NASA Glenn Research Center.
NASA requires approximately 5,000 liters of xenon with a minimum purity of 99.999% delivered in vendor-provided bottles. The xenon must meet strict impurity limits specified in Table 1, including maximum allowable contents of oxygen (≤0.1 ppm), water (≤0.1 ppm), carbon monoxide (≤0.5 ppm), carbon dioxide (≤0.5 ppm), carbon tetrafluoride (≤0.1 ppm), total hydrocarbons (≤0.1 ppm), nitrogen (≤1.0 ppm), hydrogen (≤2.0 ppm), krypton (≤5.0 ppm), and argon (≤1.0 ppm), with total impurities not exceeding 10.4 ppm. Each cylinder must be equipped with a rare gas valve or bellows-sealed valve with a CGA 580 external connection fitting, labeled with tare weight, and possess a minimum of one year remaining on its DOT certification. The procurement includes vendor responsibility for shipping costs to deliver xenon to NASA bottles and for transporting the new vendor-provided bottles containing the high-purity xenon to NASA. A Certificate of Analysis is required for each cylinder, stating the quantity of xenon in liters at standard temperature and pressure (32°F and 29.92 inches of mercury), actual measured impurity values, and measurement uncertainty for each impurity. Bottles failing to meet impurity requirements or lacking accompanying certificates of analysis will be rejected by the government.

Specifications:
The vendor will provide approximately 5,000 L of high-purity xenon to NASA for use in electric propulsion testing.
The procurement should include shipping costs for the vendor to deliver the xenon to NASA bottles and for the new vendor-provided bottles containing the high-purity xenon.
NASA requires Xe with a purity greater than or equal to 99.999% and meets the requirements for impurities listed in Table 1 measuring the impurities in each individual bottle. Each cylinder shall be fit with a rare gas valve or a bellows-sealed valve to eliminate stem leakage. The external connection shall be a CGA 580 valve fitting. Each cylinder shall be labelled with its tare weight and have a minimum of one
(1) year remaining on its DOT certification.
Table 1 Maximum Allowable Impurities
Constituent Allowable Content, measured
Oxygen (O2) ≤ 0.1 ppm
Water (H2O) ≤ 0.1 ppm
Carbon Monoxide (CO) ≤ 0.5 ppm
Carbon Dioxide (CO2) ≤ 0.5 ppm
Carbon Tetrafluoride (CF4) ≤ 0.1 ppm
Total hydrocarbons (THC) ≤ 0.1 ppm
Nitrogen (N2) ≤ 1.0 ppm
Hydrogen (H2) ≤ 2.0 ppm
Krypton (Kr) ≤ 5.0 ppm
Argon (Ar) ≤ 1.0 ppm
Total Impurities ≤ 10.4 ppm (balance xenon)
A certificate of analysis is required for each cylinder to verify purity requirements. Lot impurities or measured impurities prior to any xenon transfer are not valid. Each bottle delivered to the Government shall have a Certificate of Analysis including:
• the quantity of xenon in liters at standard temperature and pressure (after extraction of sample as required for cylinder analysis),
• the actual measured impurity values for that cylinder,
• the measurement uncertainty for each impurity, and
A liter will be defined at standard temperature and pressure conditions of 32 degrees Fahrenheit and
29.92 inches of mercury. Any bottle that fails to comply with the requirements for measured impurity or does not have an accompanying certificate of measured impurity levels for that bottle shall be rejected by the government.
