A comparison of serum electrolyte results by Technicon's Flame III and Flame IV AutoAnalyser system.

A comparison of Technicon's (Technicon, Tarrytown, N. Y., 10591) Flame III and Flame IV electrolyte Auto-Analyzer systems for the determination of Na+, K+, Cl- and CO2 in serum is described. Results from the Flame IV are determined over three periods of time and compared to those of the referee Flame III system. The Optional Digital Printer and Linearizer Modules are not used with the described system. The Flame IV AutoAnalyzer is calibrated with a multi-point calibration technique (aqueous reference standards) rather than the single-point calibration technique (albumin reference material) used by the AutoAnalyzer II. Results for the Flame IV are shown to be comparable with those for the Flame III.
