Abstract
Method and system that allows the use of water as reactant gas for internal chemical ionization in mass spectrometry. The system provides a stable water vapor pressure in the ion trap by condensation-free water vapor flow between water reservoir and ion trap. The system can be implemented by modification of any type of ion-trap mass spectrometer designed for internal chemical ionization.
