Quantification of Color-Changing Papers (M8) Using Industrial Devices and Methods

Abstract

The use of eye-readable colorimetric technology to detect chemical warfare agents dates back to the development of M8 paper by Canadian scientists in 1963. Currently, a number of studies are attempting to augment M8 paper or develop other new colorimetric indicators. In this study, we demonstrate a German commercial device, the Micro-Epsilon (Ortenburg, Germany) CFS colorSensor CFO200 sensor, and industrial methods using the International Commission on Illumination (Vienna, Austria) standardized perceptual color space known as CIELAB to document the ability to quantify sample variations in M8 paper. More importantly, we also document the level of color change in color-changing paper such as M8 when it is exposed to H-, G-, and V-class agents. This ability to quantify color change levels and their relationship to the observable differences will be essential to developing and determining the efficacy of eye-readable colorimetric technologies.
