To fit a specific application, a cheap and effective manner of measurement of chemistries in plasma‐activated water (PAW) is in demand. We propose a digital colorimetry‐based method of quantifying the long‐lived species in PAW using only smartphones and specialized software. Pin−plate discharge and surface microdischarge were used to generate the PAWs. H2O2 and NO2− were selected as representatives for the test. Various color parameters were extracted from images of a solution consisting of testing species and colorimetric reagent. Specialized curve‐fitting strategies were developed during data processing. The results were consistent with those measured by UV–Vis spectrometry, but they provided better performance and simplified operation. Additionally, the proposed PAW generator design can be integrated with the detecting module based on this method.

基于数字比色法检测血浆活化水中的长寿命物种
为了适合特定的应用，需要一种廉价，有效的等离子体活化水（PAW）中化学成分的测量方法。我们提出了一种基于数字比色法的方法，仅使用智能手机和专用软件即可对PAW中的长寿命物种进行定量。针板放电和表面微放电用于生成PAW。ħ 2 ö 2和NO 2 -被选为测试的代表。从由测试物质和比色试剂组成的溶液图像中提取各种颜色参数。在数据处理期间开发了专门的曲线拟合策略。结果与通过紫外可见光谱法测得的结果一致，但是它们提供了更好的性能和简化的操作。另外，基于该方法，所提出的PAW发生器设计可以与检测模块集成在一起。
