Abstract

1. The hydraulics of first- and second-generation AutoAnalyzers introduce lag and exponential deformations of the square wave signal expected from the colorimeter. These factors limit sampling rates by causing sample interaction. Curve regeneration carried out on Technicon Flame IV modules, using a digital approach, with a Hewlett-Packard 2100A computer, has successfully compensated for exponential deformation of sodium, potassium, chloride and carbon dioxide channels in routine laboratory use for one year. A sampling rate of 138/hr has been used; faster rates are possible. 2. Reduced sample and reagent consumption are benefits in addition to the increased analysis rate.
