Abstract
While a large primary stream () of analytes flow from a chromatographic column () to containers of a receiver (), small samples of the analytes are diverted for flow to a mass spectrometer () for analysis, by use of a transfer module (). The transfer module includes a stator () and a rotor or shuttle (). The shuttle has an aliquot passage () that initially lies in a first position where the primary stream flows through it so the aliquot passage receives a small sample. The shuttle then moves to a second position where the aliquot passage (at) is aligned with a pump () that pumps fluid out of the aliquot passage to the mass spectrometer.
