Evaluation of a random access analyser: BM/Hitachi 911

Abstract

The performance of Boehringer Mannheim’s BM/Hitachi 911 was evaluated for three months. The mean coefficient of variation (CV) of the within-run and between-run imprecision of the 16 analytes were less than 1-16% (range 0’47-2’38%) and 1-36% (range 0-62-2-93%), respectively. A linearity study for the various assays covered clinically important levels. No relevant drift was observed during an eight-hour assay nor was any sample-related carry-over detected. In all cases, the regression analyses (slopes) of the results obtained from BM/Hitachi 911 and 717 were between the extreme values of 0-94 and 1-05. During the three months of operation, no major problem was encountered. The BM/Hitachi 911 was found to be easily operated, to require minimal attention and simple daily maintenance during operation. © 1995, Hindawi Publishing Corporation. All rights reserved.
