An interfering factor in the automated analysis of calcium
Abstract:
The widespread use of stainless steel for sample probes, connectors, and sample stream splitters in autoanalyser systems can lead to significant differences in the amount of calcium available for analysis. At alkaline pH calcium can be adsorbed onto the metallic components of the sampling system, and under more acidic conditions calcium can be released. Thus an alkaline sample will have an apparently reduced calcium content, while a more acidic sample may have an apparently increased concentration of calcium. By using non-metallic components in the sampling system this source of error an be eliminated.
