FUNDAMENTAL IN DETERMINING REACTION RATE IN BIOREACTORS AND REQUIRES A PROBE DESIGNED SPECIFICALLY FOR THE BIOREACTOR ENVIRONMENT.

FUNDAMENTAL IN DETERMINING REACTION RATE IN BIOREACTORS AND REQUIRES A PROBE DESIGNED SPECIFICALLY FOR THE BIOREACTOR ENVIRONMENT. MEMBRANE COVERED D O PROBES SUFFER FROM SLOW RESPONSE TIME, LACK OF SELF-CLEANING AND A SUSCEPTIBILITY TOSTIRRING OR AGITATION RATE. ECO INSTRUMENTS PROPOSES TO BUILD AND TEST A NEW TYPE OF MEMBRANELESS D O ELECTRODE WHICH IS DESIGNED SPECIFICALLY FOR THE BIOREACTOR ENVIRONMENT. THIS NEW D O ELECTRODE WILL RELY UPON HYDRODYNAMIC MODULATION TO MAINTAIN A REGION OF LAMINAR FLOWACROSS ITS SURFACE WHICH IS INDEPENDENT OF BULK CONVECTIVE PROCESSES AND WILL USE THREE ELECTRODE VOLTAMMETRY TO SELECTIVELY REDUCE OXYGEN. HYDRODYNAMIC MODULATION PERMITS BOTH SELF-CLEANING AND DISCRIMINATION BETWEEN ADSORBED AND DISSOLVED ELECTROACTIVE SPECIES. THREE ELECTRODE VOLTAMMETRY PERMITS SELECTIVE DETERMINATION OF OXYGEN IN THE PRESENCE OF OTHER ELECTROACTIVE SPECIES.
