title: Design of quality-control specimens for use with a small multi-channel analyzer.
abstract: Specimens having linear relationships between concentration and instrument response for seven analytes were prepared for use with a small multi-channel analyzer. The specimens had inter-specimen and inter-constituent relationships that facilitated the performance evaluation of all channels simultaneously with each individual specimen. Techniques are described for use of the specimens in various aspects of quality control.
