Abstract: One embodiment provides a system, including: at least two water analyzers, wherein at least one of the at least two water analyzers is positioned upstream of a purification apparatus and wherein at least another of the at least two water analyzers is positioned downstream of the purification apparatus; at least one processor; and a memory device that stores instructions executable by the processor to: receive water analysis data from the at least two water analyzers, wherein the water analysis data comprises information related to membrane integrity; identify an algorithm for calculating membrane integrity based upon received data corresponding to system attributes; and calculate, using the identified algorithm, the membrane integrity based upon the received water analysis data. Other aspects are described and claimed.

Abstract: An embodiment provides a method for cleaning a sample cell of a turbidimeter, including: introducing an apparatus comprising a cleaning component into the sample cell, wherein upon introduction of the apparatus into the sample cell a secondary flow path out of the sample cell is opened; engaging a functionality of the apparatus to clean the sample cell; and removing a plurality of particles from the sample cell via the secondary flow path. Other aspects are described and claimed.

Abstract: Various turbidimeters are described that can detect light directly in a substantially circular, e.g., encompassing, manner such that an increased amount of scattered light from a sample vial may be detected by a light detector, e.g., a photodiode or photodiode array. In an embodiment, a substantially circular photodiode array is provided to directly detect scattered light in an arc about the sample vial. In other embodiments, light guides are provided in an arc element that guides light to a detector or detectors. Other aspects are described and claimed.

Abstract: A total organic carbon (TOC) fluid sensor (100) is provided according to an embodiment of the invention. The TOC fluid sensor (100) includes a first oxidization cell (101A), a second oxidization cell (101B), a gas permeable membrane (106) configured to allow carbon dioxide to equilibriate between the first oxidization cell (101A) and the second oxidization cell (101B), a first conductivity sensor (136A), and a second conductivity sensor (136B). The TOC fluid sensor (100) oxidizes a fluid portion in the first oxidization cell (101A) to create carbon dioxide, equilibriates the carbon dioxide between the first oxidization cell (101A) and the second oxidization cell (101B), obtains a second cell conductivity information, and determines a TOC quantity in the fluid under test from the second cell conductivity information when the first cell oxidization is substantially complete.
