Spectroscopic Analysis. There are many different types of materials analysis techniques under the broad heading of “spectroscopy”, utilizing a wide variety of different approaches to probing material properties, such as absorbance, reflection, emission, scattering, thermal conductivity, and refractive index. Spectroscopic analysis expert witnesses may opine on infrared spectroscopy and absorption spectroscopy, as well as related issues. In Atomic Absorption: Feeding the Food Safety Market, Hazel Dickson writes on food safety and the media:
Recent years have seen a change in the availability of research and information relating to food and public health. Such research is no longer only visible to scientific researchers through academic literature but is becoming more and more visible to the general public through news websites, magazine articles, and online blogs and social networking sites – for example, the U.S. Food and Drug Administration now announces product recalls though the real-time information network Twitter. In addition, the past several months have seen a wealth of articles appearing in the general public news relating specifically to trace elements in foodstuffs, including antimony and arsenic in fruit juice, lead in cocoa products, and tin in canned foods. With an ever-increasing public and consumer awareness, the demands placed on food analysis and testing laboratories has reached an all-time high.
