Additional Information:

The microscopy lab maintains scanning electron (SEM) and light microscopes for the analysis of foods, ingredients, packaging and foreign materials. Microscopic analysis can supply important information on the physical structure of the sample and its components and can be used as a tool in the identification of particulates found in food and packaging samples. The light microscopes are used to characterize and identify materials based on observed physical and optical properties. These properties can give information about function and morphology. The SEM is well suited to look at surface features and can achieve a much greater magnification than other microscopy techniques. Our SEM is also equipped with an x-ray (EDS) detector that provides information on the elemental makeup of a sample. Our lab also does FTIR analysis and can use this technique on applicable matrices to assist in further characterizing or identifying your sample. Each sample is unique and we can work with you to provide the analysis you need.
