摘要： A method of quantitatively measuring the concentration of a chemical species in a sample solution with a sensor film. A hydrogel sensor film is prepared having a chemical composition comprising an indicator that changes its optical property in the ultra-violet, visible or near-infrared spectral range upon being exposed to the chemical species in the sample solution. The film is exposed to a fixed amount of the sample solution. The concentration of the chemical species in the sample solution is quantified using the average absorbance measured from the sensor film.

摘要： Embodiments of the invention provide self-contained phosphate sensors with an analyte-specific reagent and a pH-modifier. The analyte-specific reagent includes a molybdenum salt or metal complex and a dye. The self-contained phosphate sensors can be used either in aqueous or non-aqueous solution or as a solid-state device. These self-contained phosphate sensors require no post-addition reagents to determine phosphate concentrations and the phosphate determination test requires a reduced number of procedural steps. Moreover, the self-contained phosphate sensor provides enhanced sensitivity and faster response time. Embodiments of the invention also provide a method for determining phosphate concentrations in a sample. The phosphate concentration in a sample can be quantified using a calibration curve generated by testing samples with known phosphate concentrations.
摘要翻译：本发明的实施方案提供具有分析物特异性试剂和pH-改性剂的自含磷酸盐传感器。分析物特异性试剂包括钼盐或金属络合物和染料。独立的磷酸盐传感器可以在水溶液或非水溶液中使用或作为固态装置使用。这些独立的磷酸盐传感器不需要后加剂来测定磷酸盐浓度，磷酸盐测定测试需要减少数量的程序步骤。此外，独立的磷酸盐传感器提供增强的灵敏度和更快的响应时间。本发明的实施方案还提供了一种测定样品中磷酸盐浓度的方法。可以使用通过测试具有已知磷酸盐浓度的样品产生的校准曲线来量化样品中的磷酸盐浓度。
