摘要

本文提出了一种利用消费类光栅成像设备，通过数字比色法间接测定小体积（从微升到数百微升不等）水溶液氢指数的技术。测定 pH 值不需要恒定的色标或溶液中酸碱指示剂的浓度信息。以智能手机为基础，为实验室外应用开发了一个手持式 pH 分析仪原型。酸碱度测定结果的准确性通过电位测定法和分光光度法得到了证实。

Indirect Determination of the Hydrogen Index of Small Volume Solutions by Digital Colorimetry

A technique for the indirect determination of the hydrogen index of aqueous solutions of small volumes (ranging from microliters to hundreds of microliters) by digital colorimetry with the use of consumer optical raster imaging devices is proposed. Determining the pH does not require constant color scales or information about the concentration of the acid-base indicator in the solution. A prototype of a handheld pH analyzer, based on a smartphone, is developed for out-of-laboratory applications. The accuracy of the pH determination results is confirmed by the potentiometry and spectrophotometry techniques.
