ABSTRACT:
Embodiments of the present invention are directed to devices and methods for receiving NSC Fluids having at least one analyte from a chromatograph and directing analyte ions into the vacuum regions of a mass spectrometer. The device has a housing having at least one wall defining a chamber, sample inlet, an ionization media inlet and an outlet. The sample inlet has a position in communication with a chromatograph receiving a NSC Fluid. The sample inlet receives the NSC Fluid and directs the NSC Fluid into the chamber to form a sample jet of NSC Fluid. The ionization media inlet is placed in fluid communication with a source of ionization media and directs the ionization media into the chamber and the sample jet to create analyte ions. The analyte ions are received in the mass spectrometer vacuum region orifice.
