摘要
A flow system for the determination of d-glucose in undiluted whole blood, in which segmented sample injection and on-line dialysis are used to decrease the red cell volume fraction (haematrocrit) dependence, is described. Glucose is degraded enzymatically by means of immobilized glucose dehydrogenase. The nicotinamide coenzyme (NAD+) that is present in the solution is reduced in the enzymatic reaction and is reoxidized amperometically at 0 mV vs. Ag/AgCl on a graphite electrode, modified with phenoxazinium ion. The potential use of the system for clinical analysis is evaluated. © 1990.
