Abstract: A coated capillary tube having a tunable resistance in an ion transfer device, including an inlet end in communication with an atmospheric-pressure ion source, an outlet end in communication with a vacuum region of a mass spectrometer, a body elongated along an axis from the inlet end to the outlet end, and an inside surface defining a bore having an inner diameter is disclosed. The coated capillary tube also includes a resistive coating on the inside surface of the capillary tube, in which the resistive coating includes at least one layer comprising oxides or nitrides of a metal and discrete metal particles of a different metal embedded therein.

Abstract: The invention provides metal liquid chromatography components with uniformly coated internal surfaces and methods for achieving the same. The invention addresses the problem of corrosion or interference of metal components in the flow path for LC analyses in which the sample interacts with metal ions or surfaces. The invention also alleviates the difficulties in coating very long metal tubes and very small metal channels with an inert, continuous coating that adheres well to metal surfaces. The metal flow path is rendered inert by the coating, and thus compatible with bioanalytical separations, for example, by using a vapor phase deposition process to coat the inner surfaces with a coating that continuously covers all metal surfaces in the flow path.
