Assessment of the Chemetrics analyser

The Chemetrics computer controlled chemistry analyser was assessed for its suitability as a general laboratory instrument at this laboratory on behalf of the Committee for Evaluation of Kits and Instrumentation of the Australian Association of Clinical Biochemists. The Chemetrics is manufactured by Chemetrics Corp., La Jolla, California, USA. To provide additional information on the system, four of the kits recommended for the Chemetrics by the Australian distributor, Calbiochem-Behring Aust. Pty, Ltd., were used to produce whole system performance data. Only those sections of the kit evaluation having a direct bearing on the total system performance are reported here. The procedure for assessment was based upon the work of Broughton [1], Westgard [2], Barnett [3] and Logan [4], and modified in the light of our own experience. A detailed technical evaluation is included as part of the evaluation procedure. Figure shows a schematic diagram of the instrument.
