对于资源有限的环境，数字成像设备可以成为前景看好、灵敏且经济实惠的化学传感器。使用了铁的三种颜色反应模型，并使用一个仅由相机、试管和白纸漫射器组成的简单平台进行监测。一台台式扫描仪和一台手机相机也被用作成像设备。分析捕获的图像以获得RGB强度(红、绿、蓝)，并进一步将其转换为灰度级、CMY(青色、洋红、黄色)、XYZ(Y：亮度，XZ：色度平面值)和YXY色彩空间(Y：亮度，XY：色度值)分析信号的相应信号。在校准曲线线性度和检出限方面，使用YXY信号的优雅方法超过了基于RGB、灰度、CMY和三刺激值XYZ数据的方法，并与用于评估复杂环境样品中的铁的复杂分光光度计所获得的数据进行了很好的比较。该方法的简单性、敏感性和成本效益使其适用于设备简陋的实验室和当地贫困社区。
Digital imaging devices can be promising, sensitive, and cost-effective chemical sensors for resource-limited settings. Three model colour reactions of iron were used and monitored using a simple platform consisting only of a camera, a cuvette, and a white paper diffuser. A desktop scanner and a mobile phone camera were also used as imaging devices. Captured images were analysed to obtain the RGB intensities (red, green, blue) and were further converted into the corresponding signals of the grayscale, CMY (cyan, magenta, yellow), XYZ (Y: luminance, XZ: chromaticity plane values) and Yxy colour spaces (Y: luminance, xy: chrominance values) analytical signals. The elegant procedure utilizing the Yxy signals surpassed those based on RGB, grayscale, CMY and tristimulus XYZ data regarding the calibration graph linearity and detection limit and compare well with those data obtained from a sophisticated spectrophotometer for assessing iron in complex environmental samples. The simplicity, sensitivity and cost effectiveness of the approach make it suitable for poorly equipped laboratories and locally deprived communities.
