  • Publication number: 20180059015
    Abstract: A personal liquid analysis system includes a portable liquid analyzer device, a mobile application as a user interface, and a cloud server for data analysis. The compact and portable liquid analyzer device is integrated by miniaturized near-infrared (NIR) optical sensors setup for spectroscopy measurement from a sample cell, control circuits, I/O user interface modules and wireless communication modules. The analyzer can be used to collect NIR spectra data from a liquid sample in the sample cell, and to transmit the data to a cloud server where compositional information is calculated, and presented to the user on the device and/or on a mobile application. The personal liquid analysis system enables the user to rapidly acquire qualitative and/or quantitative compositional information from liquid samples for a wide range of applications.
