Multi-parameter water analysis system with a water parameter sensing device configured to wirelessly provide detector data and a smart phone displayable indicator of water analysis test results that are calculated by an analysis application that is updateable via a cloud-based data resource to account for a manufacturing change in indicator chemistry and/or an improvement in test result display. The water parameter sensing device includes an optical sensing apparatus configured to detect light from each of a plurality of indicators for different parameters when the indicator and a chemical parameter are exposed to each other, a processor to process information of the detected light, and wireless communication circuitry for communicating detector data based on the information about the detected light to a remote device. Social networking of water quality data allows sharing to other users.

An automatic analysis apparatus capable of improving detection sensitivity is provided. An optimum photometer between a light-scattering photometer and an absorptiometer based on a concentration range may be decided. A standard solution is measured multiple times at a normal calibration and a calibration curve is created. Calibration curves are individually created for an absorptiometer and a light-scattering photometer from the minimum and maximum measured values of the concentrations of each standard solution. The upper and lower limits of a standard solution concentration are computed from the minimum/maximum calibration curves. Sensitivity may be computed by using calibration parameters. Whether to use a concentration by absorption or a concentration by scattered light is decided based on the computed sensitivity. The computed sensitivities are compared between the concentration by absorption and the concentration by scattered light, and the use of the concentration of a higher sensitivity is decided.

A sample-processing system that improves total system processing efficiency, and reduces a sample-processing time, by establishing a functionally independent relationship between a rack conveyance block with rack supply, conveyance, and recovery functions, and a processing block with sample preprocessing, analysis, and other functions. A buffer unit with random accessibility to multiple racks standing by for processing is combined with each of multiple processing units to form a pair, and the system is constructed to load and unload racks into and from the buffer unit through the rack conveyance block so that one unprocessed rack is loaded into the buffer unit and then upon completion of process steps up to automatic retesting, unloaded from the buffer unit. Functional dependence between any processing unit and a conveyance unit is thus eliminated.
