Abstract:
1. A fluid transfer module for transferring a sample slug of dissolved analytes from of a high rate primary stream of dissolved analytes to a secondary stream leading to an analyzer for analysis of the analyte, said transfer module comprising: a stator device having a first stator face, and defining a rotor device having a rotor face in fluid-tight contact against said first stator face at an interface between, said rotor face defining an aliquot channel in fluid communication with said interface, wherein, in a first rotor position, said aliquot channel is aligned in fluid communication with said communication opening of the primary passage to acquire a sample slug of analyte therein, and in a second rotor position, said aliquot channel is aligned with both said first communication port of the upstream secondary passage and second communication port of the downstream secondary passage to enable transfer of substantially all of the sample slug in a uniform flow manner through the downstream secondary stator passage to the analyzer.
