Note: Liquid argon does not detect moisture content
Frequently Asked Questions (FAQ)
What is the guaranteed purity level of this Argon product?
The minimum guaranteed purity level of Argon (Ar) is 99.999% by volume fraction (10-2 ≥ 99.999).
What are the maximum thresholds for Oxygen and Nitrogen impurities?
The maximum allowable volume fraction is 1.5 × 10-6 for Oxygen (O2) and 4 × 10-6 for Nitrogen (N2).
How are carbon impurities (CO, CO2, CH4) restricted in this specification?
Carbon contaminants are maintained at minimal levels: Methane (CH4) is limited to ≤ 0.4 × 10-6, while Carbon Monoxide (CO) and Carbon Dioxide (CO2) are each limited to ≤ 0.3 × 10-6.
What is the moisture (H2O) content specification?
Water content is restricted to ≤ 3 × 10-6 by volume fraction for standard delivery.
Why is moisture content omitted for liquid argon?
According to the technical standards note, moisture content is not detected/measured in the liquid argon phase.
What units do 10-2 and 10-6 represent in these technical properties?
In technical gas specifications, volume fraction 10-2 corresponds to percentage (%), while 10-6 corresponds to parts per million (ppm).
