Investigation of Repeatability and Error Instability Analysis of Tissue Biosensor

摘要

Co-substrate sensitive amperometric system for the measurement of dopamine has been constructed. The repeatability of constructed biosensor has been investigated. A formulae for the total instability has been obtained. The instability due to inner factors has led to instrumental error of instability of the system. The analysis of the error from the instability has been carried out. As an active membrane immobilized banana tissue on dederone screen has been used. The measurements are conducted in the normal working conditions. A uniform scale has been chosen.
