Primary measurement standards for trace moisture in multiple gases: extension of gas species to He and O 2

The National Metrology Institute of Japan developed a multi-gas trace-moisture generator which was designed for generating trace water vapor (trace moisture) in multiple gases. Using this system, we previously developed primary measurement standards for trace moisture in N 2 (10 nmol mol −1 –5 μmol...
