Interpretation

Set limits and define action

The real value of monitoring microbiological water quality lies in the detection of changes from those expected, based on frequent, long term monitoring. Therefore, the starting point for gaining the full potential of the Bactiquant technology is to establish baselines for a normal operation in Critical Control Points. It is then possible to use the historic data from a critical Control Point to calculate local operational limits that define a normal situation, an observation limit and an action limit, based on the principles of Statistical Process Control, described in ISO 11462-1:2001(E). The observation limit and the action limit are defined as analysis results that are more than 2 standard deviations and 3 standard deviations from the historic average, respectively.  

The Bactiquant database software

 Use the Bactiquant database software to handle data according to the principle of Statistical Process Control. The software is 21 CFR part 11 compatible (FDA standards). The software allows a quick overview of historic data from Critical Control Points. The software allows GIS/MAPinfo integration providing a State of the art" monitoring capability.
