  • Metastable CID
    Publication number: 20110210243
    Abstract: Systems and methods of generating ions at atmospheric pressure are presented. These systems and methods include spatially dependent analysis of a sample using an effusive ionization source. Systems and methods of isolating samples at atmospheric pressure are presented. These systems and methods include using a barrier to prevent metastables or electrons from an effusive ion source from reaching a sample unless the sample is in an analysis position. Systems and methods of using metastables in collisionally induced dissociation are presented.
    Type: Application
    Filed: April 25, 2011
    Publication date: September 1, 2011
    Inventors: Steven M. Colby, O. David Sparkman
