A sensor for gas species in water includes two membranes separating first, second and third chambers. The first and second chambers are separated by an ion exchange membrane, and the second and third chambers are separated by a gas permeable membrane. Water electrolysis in the first and second chambers provides analyte-ions corresponding to an analyte being detected that pass through the ion exchange membrane from the first chamber to the second chamber. Within the second chamber, these analyte-ions generate analyte via the electrolysis. Analyte in the second chamber passes through the gas permeable membrane to arrive at the third chamber. Within the third chamber, the analyte-ion is generated chemically from the analyte. Electrical detection of the analyte-ion in the third chamber provides sensing of the analyte present in the first chamber.

This device and method can be used for monitoring and control of the milk quality, monitoring and control of the health of dairy animal and herd management and decision-making. The device for milk analysis is composed of tanks for water and reagent, a milk probe, a unit for analysis and management and a unit for transfer and monitoring with software applications. The samples are mixed in a mixing flask, previously subjected to an ultrasonic and temperature measurement as well as a measurement of conductivity. The movement of the fluid through the system is performed by peristaltic pumps. The actual measurement takes place at the outflow of the measured sample in one of two funnels with elongated ends with integrated capillary of the ends of each. To the funnels are mounted a pair of motion sensors.

An ultrapure water (UPW) generation and verification system can include a cleaning chemical station, a cleanup column, a conductivity verification station, and a holding reservoir, in fluid communication with one another. The cleaning chemical station can be configured to selectably permit a flow of water to pass therethrough to the cleanup column or to block the flow of water and instead deliver a cleaning chemical to the cleanup column. The conductivity verification station can be configured to selectably perform at least one of the following: permit water to flow from the cleanup column to the holding reservoir; direct fluid to waste; or test the conductivity of the water for a purity level.
