Over the last few years there has been considerable interest in the application of impedance measurements for monitoring microbial activity (Ur and Brown 1974). A number of publications have appeared which report that the potential sensitivity of such systems may surpass any of the more classical bacteriological techniques (Bakhtiar and Selwyn 1982). Yet despite these encouraging results the technique until now has not entered into general microbiological use but has instead remained in the domain of scientific curiosity. It is therefore of interest to examine whether this delay has been caused by inherent deficiency in the method or is due to the normal process of transformation of a technical innovation into a commercially available system.
