摘要： This invention relates to methods and apparatus for determination of ion concentrations, particularly in downhole water from hydrocarbon wells, aquifers etc. It is useful in a wide range of applications, including predicting the formation of scale and fingerprinting waters from different sources. More particularly, the invention relates to the use of ligands whose electronic configuration is altered by the binding of the scaling ions within a water sample. These alterations are detected electrochemically by applying varying potential to electrodes and measuring current flow as potential is varied, from which is derived the concentration of scaling ions in the fluid.

摘要： The invention provides a single colorimetric reagent for the measurement of oxidising agents such as free chlorine in a liquid sample which contains a food dye, whereby the oxidising agent undergoes a reaction with said food dye. A preferred food dye is Brilliant Blue FCF. There is also provided a control system for regulating the volume of reagent added to a fixed volume of sample according to a control algorithm to give a chosen excess of a reagent compound beyond that required to stoichiometrically react with the target analyte in the sample. Also disclosed are single reagents for colorimetric determination of total alkalinity and calcium hardness.

摘要： Prior to adding detergent or chelant, the conductivity of water in a washing chamber is measured. The maximum concentration of hard water ions that could correspond to the measured conductivity is determined, i.e., it is assumed that all of the conductivity is from calcium and/or magnesium ions in the water even though other ions may in fact be contributing to the measured conductivity. Enough chelating agent is added to the chamber to sequester this maximum concentration of hard water ions and the conductivity is measured again. Using the two conductivity measurements, the actual concentration of hard water ions is determined. A chelant factor based on the actual concentration of hard water ions is then used to determine the amount of chelant to be added for subsequent wash cycles to sequester all of the hard water ions.

摘要： An apparatus for determining total hardness in a fluid stream utilizing a first and second sodium ion selective electrode (ISE). The ion selective electrodes are in electrical communication with one another, having first and second reference electrodes, respectively, with a salt bridge therebetween, where the first ISE receives hard water and the second ISE receives soft water. A least one drain receives outflow from effluent fluid from the first and second sodium ISE sensors.

摘要： The present invention is directed to a water condition monitoring device and related methods of use that significantly reduce the cost of the water condition monitoring devices by replacing the expensive and bulky multiple sensor electrodes of currently available devices with a single set of two or three metal electrodes to detect and/or measure such water quality parameters as pH, electric conductivity, temperature, and dissolved oxygen content. A microcontroller activates each sensor one at a time in a continuous loop, processing the sensor signals into near real time water condition data, which may be stored, displayed, or sent to a remote location for storage or display.
