Lovibond® Water Testing Tintometer® Group

PTSA and Fluorescein

Industrial Water Treatment Systems are complex and dynamic and, as such, require optimum knowledge and treatment to address their variability. The correct treatment and, therefore, the correct dosage of treatment chemicals into such systems are essential for system maintenance and performance.

The improper dosing of these chemicals can lead directly to serious problems including, but not limited to: reduced heat exchange; increased maintenance; and reduced plant efficiency through the formation of scale, corrosion, and bio film build up.

By adding PTSA to the formulation, the fluorescent response of the tracer is proportional and graphically linear, between specific concentration ranges, to the concentration of the chemical with which the system is dosed. Measurement and monitoring PTSA concentration, unlike those traditional methods mentioned above, does not require additional chemical reactions but instead can be directly measured using fluorometry. This method of analysis allows measurements online, in the field and in the laboratory to be expedited quickly and routinely, enabling real time product dose analysis, reduction in detection and reduction of response times.
