  • Separation and analysis of sample components
    Patent number: 6909091
    Abstract: The invention describes a new integrated separation and analysis system for analysis and separation of at least one sample component, comprising a mass sensitive detector (1) with ionization source (2), at least one mobile solid phase (3), at least one sample component (4), one transport system (5) where the mobile solid phase and the sample component are transported, and at least one transport fluid (6). The sample component is separated at the interface between the transport and the mass sensitive detector. Also, a method for analysis and separation of sample components is included, utilizing the mentioned integrated separation and analysis system. According to the method, the mobile solid phase and the sample are separated before the mass analyzer, and the sample components are transported towards the mass analyzer.
