ABSTRACT:
An interface for an in-line chromatograph mass spectrometer includes a mixing tee having a first inlet, a second inlet, and an outlet with the first inlet in fluid communication with the outlet of the chromatograph; a back pressure regulator having an inlet and an outlet with the inlet in fluid communication with the outlet of the mixing tee; a coaxial splitter having an inlet, a first outlet, and a second outlet, wherein the inlet of the coaxial splitter is in fluid communication with the outlet of the pressure regulator; a mass spectrometer having an inlet in fluid communication with the first outlet of the coaxial splitter. The interface regulates the flow into the spectrometer without undesirably increasing any back pressure to the chromatograph.
