Abstract

In apparatus for analysis of liquids of the type which uses disposable discrete analyte dedicated substrates incorrect results arising if the substrate is inoperable through being defective or dedicated to a different analyte from that being measured, are avoided by combining the response measuring means used to monitor the response of the substrates to applied analyte samples with testing means adapted to distinguish defective substrates or wrongly dedicated substrates and initiate their removal. Defective substrates may be detected by failure to react with analyte and a resulting absence of differential signal and wrongly dedicated substrates comprising electrodes may be detected by measuring electrode impedance.
