    摘要： Disclosed is a reagent strip comprising test region(s) and reference region(s). The reference region(s) display a predetermined response to a range of possible concentrations of an analyte applied to the corresponding test region(s). Furthermore, the reference region(s) and the test region(s) are arranged on the reagent strip so as to facilitate analysis of a qualitative state of the analyte and optionally, calculation of a quantitative value of the analyte at point-of-collection. Also disclosed is a method of manufacturing such reagent strips, first involving printing the reference region(s) and the test region(s) in a continuous and alternating series on a test strip precursor substrate. The method also involves cutting the test strip precursor substrate perpendicularly to the printed columns to obtain one or more reagent strips. Also disclosed is a method encompassed in a mobile application for determining a qualitative state and optionally calculating a quantitative state of the analyte.

    摘要： A method of monitoring and controlling hardness in an industrial water system is described and claimed. The method requires the use of a Compound that develops a separate detectable fluorescent signal in the presence of soluble hardness. A fluorometer is used to detect this separate detectable fluorescent signal of the Compound. The separate detectable fluorescent signal is used to ascertain the amount of soluble hardness present in the industrial water system. Another aspect of the instant claimed invention is the ability to determine whether the soluble hardness is calcium or magnesium based.
