Evaluation of the Kodak Ektachem DT60 analyser for sodium, potassium, glucose and urea

The Kodak Ektachem DT60/E analyser is a desk-top analyser which uses thin-film ’dry’ chemistry technology to perform colorimetric and potentiometric analyses. The analyser is simple to operate and the slides are claimed to be stablefor up to oneyear if stored at 4 C. Calibration is said to be required only once every three months. Results presented in this paper substantiate these claims and show that the Ektachem DT60/E produces results which are comparable in terms ofbias andprecision with currently used methods for sodium, potassium, urea and glucose. The instrument might have an application within the laboratory for emergency work as well as for out-of-laboratory testing.
