High Purity Trending Analysis
High purity water production is critical to the successful production of pharmaceuticals.  Stainless steel pipes build up "rouge" on their interior surfaces with time as the high purity water leeches the trace metals from the stainless steel.  This rouge can reach a critical level and these elements can start to appear in the water stream in elevated levels.  Additionally, water purification treatments can begin to fail and also allow elevated concentrations.  These effects can be quite gradual, and at the part per billion level, difficult to separate out the "signal to noise".  This tool can spot very subtle trends in the trace elements, and help predict when the expensive "derouging" process is required.  This tool also allows the user to compare the performance of different water systems.  The tool currently has over 22,000 data points, providing a large data set to allow for relative performance measurements.
Data entry is quick and easy.  The output is quite extensive.  Some output reports are illustrated here:

There is a detail report on every sample point:
