Abstract:
Miniature, rugged Chemfet sensors have been developed by coating field-effect transistors with ion-sensitive membranes. These sensors have been combined with a flow injection analysis manifold to demonstrate feasibility of a small portable system capable of simultaneous determinations in 10 seconds of hydrogen, potassium and calcium ion activities in 20 microliters samples of whole blood, serum or dialysate.
