  • Method for interfacing liquid chromatography-mass spectrometry systems
    Patent number: 5447553
    Abstract: Close coupled momentum separator with integral removable source volume for particle beam liquid chromatography/mass spectrometry is provided. The inventive PB LC/MS system comprises a momentum separator wherein the skimmers are designed to accommodate the particle beam conical dispersion so as to minimize the number of particles lost in the separator. In addition, the exit of the momentum separator is closely coupled to the entrance of the MS source volume. The PB LC/MS system demonstrates improved linearity in signal and enhanced sensitivity.
    Type: Grant
    Filed: October 19, 1994
    Date of Patent: September 5, 1995
    Assignee: Hewlett-Packard Company
    Inventors: James A. Apffel, Jr., Robert G. Nordman, Mirko Martich
