Contactless Optical Liquid Identifier
ACS Omega, 2023 This paper presents the development of a portable device that can be used for liquid identification using the concept of Beer-Lambert law. The final device can recognize up to 30 different materials in their liquid state and provides some other useful features that can enhance its operation.
