Integrated analytical systems and methods and / or other process systems for simultaneously monitoring biological and / or chemical species coexisting in water are disclosed. The system provides a sample-volume controlled sensor array, which includes, in addition to the fluid delivery device, a plurality of optical sensor elements that determine the presence and the total concentration of a plurality of analytes in the process system. do. Delivery means are provided for delivering a meter of sample fluid to the sensor array. Image identification algorithms are provided for identifying analytes based on image intensity, color pattern, positional arrangement, and the like. The method includes a multivariate optimization algorithm for analyzing multiple sensor responses. This algorithm yields analytical results that would not normally be obtained without full system or variable compensation. This enhanced array reaction can then be used to measure, monitor and control the concentration of the analyte in a chemical or biological sample or water system. |
