摘要:
A method apparatus wherein a plurality of electric fields and of orthogonal spray configurations of vaporized analyte are so combined as to enhance the efficiency of analyte detection and mass analysis. The method and apparatus provides reduced noise and increased signal sensitivity in both API electrospray and APCI operating modes.
