Quality regulation charts

Quality regulation charts, also called regulation charts or control charts, permit the continuous control of precision and correctness in a defined control period with the help of a simple graphic presentation. For this purpose one or more control samples are analyzed additionally in each series of analyses. The results of these analyses or the statistical identification data derived from these results are continuously entered in a diagram. 

The usage of quality control charts in the field of quality assurance is based on the assumption that the determined results are distributed normally. Typical control charts used in a LIMS for routine analysis are, for example, the Shewhart charts for mean and blank value control, the retrieval frequency control chart, and the range and single-value control chart [19]. Quality regulation charts can be displayed graphically in the system or exported to spreadsheet programs.
