Ultra high purity gas analysis using atmospheric pressure ionization mass spectrometry
A method for measuring the gaseous concentration of at least one selected gas from a plurality of gases comprising hydrogen. The method comprises converting at least one of the selected gas into a measurable gas using a catalyst-oxidizer, and analyzing the measurable gas by atmospheric pressure ioni...

| Zusammenfassung: | A method for measuring the gaseous concentration of at least one selected gas from a plurality of gases comprising hydrogen. The method comprises converting at least one of the selected gas into a measurable gas using a catalyst-oxidizer, and analyzing the measurable gas by atmospheric pressure ionization mass spectrometry to a sensitivity of less than 1 ppb. |
