Miniaturization in NIR Spectroscopy Reshapes Chemical Analysis

Facebook Twitter LinkedIn Email

Smartphone-based sensor technology, in conjunction with chemometrics and machine learning, is advancing applications such as agricultural and environmental field monitoring.

KRZYSZTOF B. BEC AND CHRISTIAN W. HUCK, UNIVERSITY OF INNSBRUCK

Near-infrared (NIR) spectroscopy has been used in groundbreaking research in many of the life sciences1 due to its capacity to rapidly determine and analyze the composition of materials. Bulky instruments with limited portability, however, have kept the technology from being used in field applications. Current trends in miniaturization, however, have opened up new realms in which NIR spectroscopy would never have functioned years ago, providing on-site, flexible, and accurate tools for agricultural and environmental analysis and food quality inspection. This is especially true in the herbal...Read full article
