    • A method and device for detecting an analyte in a solution or compound mixture use colorimetric detection to detect the quantity of an analyte in the solution or compound. The analyte sensor demonstrates a clear change in peak light absorption wavelength as a function of the stoichiometric relationship between the analyte sensor and the analyte. The method involves combining the analyte sensor and the analyte in solution and observing a color change of the mixture. Additionally, predefined amounts of the analyte sensor can be added until color change is detected and the quantity of analyte can be determined as a function of the total amount of analyte sensor in the mixture. Alternatively, a device having multiple wells or compartments, each with a different concentration of the analyte sensor. The analyte sample can be introduced to each well and the well that demonstrates the color change can, from its know analyte sensor concentration, be used to quickly and accurately determine the concentration of the analyte.
    • 用于检测溶液或化合物混合物中的分析物的方法和装置使用比色检测来检测溶液或化合物中分析物的量。 分析物传感器表现出峰值光吸收波长的明显变化,作为分析物传感器和分析物之间的化学计量关系的函数。 该方法包括将分析物传感器和分析物结合在溶液中并观察混合物的颜色变化。 另外,可以添加预定量的分析物传感器,直到检测到颜色变化,并且可以将分析物的量确定为混合物中分析物传感器的总量的函数。 或者,具有多个孔或隔室的装置,每个具有不同浓度的分析物传感器。 可以将分析物样品引入每个孔,并且证明颜色变化的孔可以从其已知的分析物传感器浓度用于快速且准确地确定分析物的浓度。
