A Bakable Changeover Valve for High Precision Mass Spectrometric Comparison of the Isotopic Composition of Gases

The construction of a bakable changeover valve for high precision mass spectrometric comparison of the isotopic composition of gases is described. The leakage across the valve seats is about an order of magnitude smaller than the values published for similar valves in use, and the ``mixing correctio...

description The construction of a bakable changeover valve for high precision mass spectrometric comparison of the isotopic composition of gases is described. The leakage across the valve seats is about an order of magnitude smaller than the values published for similar valves in use, and the ``mixing correction'' which can be a significant correction to the experimental data is negligible.
