YSI Technology – Immobilized Enzyme Electrodes To measure a substrate of interest, one or more enzymes are immobilized between two membrane layers, polycarbonate and cellulose acetate. The substrate reacts with the enzyme(s), producing hydrogen peroxide, which passes through the cellulose acetate to an electrode with a platinum anode. Here the hydrogen peroxide is oxidized. The resulting current is proportional to the concentration of the substrate. YSI membranes contain three layers. The first layer, porous polycarbonate, limits the diffusion of the substrate into the second (enzyme) layer,...

[ 8 0 0 . 6 5 9 . 8 8 9 5 ] 5 YSI Technology – Fluid Management Technology The YSI 7100 MBS uses sensors combined with Multitask Intelligence software to monitor calibration solutions, buffer flush solutions, and sample aspirations. Calibration standard and buffer solution labels are bar-coded for easy entry of information into fluid management software. Shelf life and working life information are continually monitored during operation; messages alert the user when reagents require attention. In addition, fluid levels are monitored. The 7100 automatically searches for reagent bottle status and...
