  • Electrospray and atmospheric pressure chemical ionization sources
    Patent number: 6060705
    Abstract: Improvements have been made to the Electrospray and Atmospheric Pressure Chemical Ionization source chambers interfaced to mass spectrometers to simplify source performance optimization and source operation and to improve system sensitivity. The atmospheric pressure ion source procedure for optimizing performance has been simplified by adding windows along the sides of the atmospheric pressure ionization chamber allowing direct viewing of the Electrospray and Atmospheric pressure ion sources during operation. A cylindrical lens which extends along the side walls of the atmospheric pressure chamber has been configured to be semitransparent for viewing into the chamber. This cylindrical shaped side lens is electrically isolated from the Electrospray liquid introduction needle and Electrospray chamber endplate.
    Type: Grant
