  • Techniques for checking state of analyzers
    Patent number: 11249059
    Abstract: An automated method of monitoring a state of an analyzer is provided including a mass spectrometer (MS) with an electrospray ionization (ESI) source coupled to a liquid chromatography (LC) stream, including monitoring an electrospray ionization current of the ESI source and identifying a condition of multiple conditions of the analyzer based on the monitored ionization current of the ESI source, one of the conditions being a presence of a dead volume in a liquid chromatography stream of the analyzer downstream of an LC column of the LC stream.
    Type: Grant
    Filed: August 14, 2020
    Date of Patent: February 15, 2022
    Assignee: Roche Diagnostics Operations, Inc.
