Gaseous Mixtures of Hydrogen, Deuterium, and Helium-3 Produced by a Partial-Pressure Mixing System

摘要

A partial-pressure gas mixing sytem was modified to prepare high-accuracy hydrogen, deuterium, and helium-3 gas mixtures as qualification standards for acceptance tests to be performed on a mass spectrometer. Accuracies (3 sigma) of 0.22% relative or less are estimated for total components. (ERA citation 04:014151)
