Laboratory evaluation of the Boehringer Mannheim "Diagnostic M" automated discrete analyzer

We evaluated a new multiple-channel chemistry analyzer, the Boehringer Mannheim "Diagnostic M." This instrument can perform 25 tests at the rate of 120 1.3-mL serum samples per hour. The instrument may be run in either a profile mode or single-test mode. In the single-test mode only the necessary reagent is pumped. the instrument is computer controlled. We compared it with the Technicon SMAC, SMA 12/60, and SMA 6/60. It demonstrated excellent precision, linearity, lack of interference, ease of operation, and satisfactory comparison with values obtained by the Technicon methods.
