Detecting and Identifying Food Colorants with SERS
Lili He, an associate professor in the Department of Food Science at the University of Massachusetts, Amherst, focuses on developing and applying advanced analytical techniques to solve critical and emerging issues in food science. Recently, that focus has turned to using surface-enhanced Raman spectroscopy (SERS) in the detection, analysis, and identification of both natural and artificial food colorants. Dr. He recently spoke to Spectroscopy about that work.

Organic Nitrogen Compounds, Part I: Introduction
So far, we have restricted our discussion to organic functional groups that contain carbon, hydrogen, and oxygen, with past columns addressing the theory of infrared spectral interpretation of C-H bonds, C-O bonds, and the C=O functional group. We now turn our attention to interpretation involving organic nitrogen compounds.
