Abstract: Total analysis systems and methods for simultaneously monitoring a suite of biological and/or chemical species in water and/or other process systems are disclosed. The system provides a sample-volume controlled sensor array comprising a fluid delivery device and a plurality of optical sensor elements for determining the presence and total concentrations of multiple analytes in the process system simultaneously. Image identification algorithms are provided for identifying the analytes based on image intensity, color pattern, positional arrangement, and the like. The methods incorporate multivariate optimization algorithms to analyze multiple sensor responses. This produces analytical results that are typically difficult to obtain without full system or variable compensation. The improved array response may then be utilized to measure, monitor, and control the concentration of analytes in the chemical or biological sample or water system.

Abstract: An apparatus and method for the monitoring and measurement of chemical and/or biological deposition in heat exchangers and other fluid processing vessels. The new and original sensing system includes at least two hollow fluid vessels conductively mounted across a constant heat transfer path. Thin film heat flux sensors are attached to a heat transfer surface of the vessels in order to measure changes in differential heat flux that occur when deposition begins to accumulate in the vessel. In this way, it is shown that differential heat flux measurements can be used to detect and measure the early onset of chemical and/or biological deposition.
