Abstract

New wall jet and flow-through cells have been developed which can be used for flow-injection analysis using chemically modified ion-sensitive field-effect transistors (CHEMFETs). In these designs traditional bonding and encapsulation with epoxy resin have become superfluous. This ISFET chip has been designed to meet the requirements of these two cell types. Measurements with plasticized PVC-valinomycin-modified CHEMFETs in these flow cells are presented. The effects of flow-rate and sample size on the recorded peak were investigated. The operational performance of the wall jet and flow-through cells were compared; the recorded peaks with the wall jet cell are less symmetrical than those with the flow-through cell.
