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.
