Co-Sense for BA








            Basic Concept of Co-Sense for BA


            The Co-Sense for BA automatically and seamlessly performs all processes from sample pretreatment to analysis. This is achieved using
            a column-switching HPLC system equipped with the innovative Shimadzu Shim-pack MAYI-ODS pretreatment column and a unique
            on-line dilution bypass channel design.


               Trapping and Concentration
            The dilution pump is used to dissociate large and small molecules to increase recovery of target analytes. This has the effect of
            breaking up large and small molecule complexes. This automatic dilution process ensures reliable trapping and concentration of
            target components by suppressing their interactions with the matrix and the impact of the sample solvent.

               Analysis

            Once unwanted constituents have passed through the trapping column to waste, the target compounds are removed by a second
            independent gradient. Valve switching is used to transfer the target compounds through the second dimension column for analysis
            detection.
