Abstract
Three autoanalysers, the EPOS 5060, ERIS 6170 and the Analyst, were evaluated for their adequacy for use in laboratories attached to Saudi ‘polyclinics’. All the analysers showed comparable within-batch imprecision. The Analyst was found to be the most useful because it was simple and practical and because its throughput time was faster than the other two analysers. The EPOS 5060 would be more suitable for screening large numbers of samples for single parameters; and the ERIS 6170 essentially suits normal routine chemical laboratory work.
