摘要：Methods and apparatuses are described for determining the presence of ananalyte in a sample suspected of containing the analyte. The method comprises

contacting a concentrate of a determinable element capable of being detected by meansof a semiconductive electrode with the electrode in the presence of a relatively largevolume of an assay medium. The determinable element is present in the concentrate inthe amount related to the amount of analyte present in the sample. The volume of themedium in diffusive communication with the concentrate is then reduced and the

determinable element is detected by means of the effect that the determinable elementhas on the semiconductive electrode.
