PROCESS AND APPARATUS FOR ADDING A REAGENT TO A CURRENT OF A LIQUID VEHICLE IN CIRCULATION, PARTICULARLY FROM A CHROMATOGRAPHIC COLUMN AND IN THE FIELD OF FLOW INJECTION ANALYSIS.

摘要

P APPARATUS AND METHOD FOR INTRODUCING A REAGENT32 INTO AN EFFLUENT VEHICLE11 OF LIQUID CHROMATOGRAPHY OR A VEHICLE11 RESULTING FROM AN ANALYSIS BY INJECTION OF FLOW THANKS TO A TRANSFER BY PENETRATION THROUGH A POROUS MEMBRANE42 INCLUDED BETWEEN 125A AND 5000A AND A SURFACE IN CONTACT WITH SAID VEHICLE 11 COMPRISED BETWEEN 0.2MM AND 150MM, TO INCREASE THE SENSITIVITY OF DETECTION AND REDUCE THE SPREAD OF THE STRIP OF THE SAMPLES. IT IS ADVANTAGEOUS THAT THE EFFLUTING VEHICLE HAS TO MOVE THROUGH A SELF-PRESSURIZED OR EXTERNALLY PRESSURIZED REAGENT ADDITION DEVICE. /P
