Mass rate attenuator

摘要: While a large primary stream ( 24 ) of analytes flow from chromatographic column 20 to containers receiver 108 ), small samples the are diverted for mass spectrometer 54 analysis, by use transfer module 102 ). The includes stator 110 and rotor or shuttle 114 has an aliquot passage 120 that initially lies in first position where flows through it so receives sample. then moves second (at 122 is aligned with pump 134 pumps fluid out spectrometer.
