  • Device for automated coupling between a micro-chromatograph and a mass spectrometer comprising a temperature adjustment
    Patent number: 7148475
    Abstract: An instrument including a chromatographic column with a final detector and a mass spectrometer. A temperature of an interface including an output tube and a capillary tube adjusting the flow to the spectrometer is adjusted using a leakage flow or pressure sensor outputting data to a control module that adjusts the interface temperature to equalize flows in the tubes.
