Tandem differential mobility spectrometers and mass spectrometer for enhanced analysis

The invention relates generally to systems, methods and devices for analyzing samples and, more particularly, to systems using tandem differential mobility spectrometers in combination with a mass analyzer to enhance the analysis process of constituents of a sample.

The present invention is directed to a flow splitter that includes an outer fluid conduit for receiving an incoming fluid flow that is the bulk flow of effluent from a liquid chromatographic column, flowing at an input flow rate. The flow splitter further includes an inner fluid conduit coaxially mounted within the outer fluid conduit so that a portion of the incoming fluid is split off into the inner fluid conduit and flows into the input end thereof. The inner fluid conduit extends beyond the exterior of the outer fluid conduit to provide an output fluid flow having an output flow rate that is less than the input flow rate. The outer fluid conduit further includes a fluid outlet that provides an outlet for the portion of the incoming fluid that is not split by the inner fluid conduit. A restriction valve can be coupled to the fluid outlet to finely adjust the output flow rate. The input end of the inner fluid conduit is positioned so as to be substantially free of turbulence from the fluid outlet.
