Identification of Organic Particles

Minute amounts of organic contaminants can be extremely difficult to classify. At Microtrace, we utilize a combination of chemical and optical properties to characterize, constrain, and identify microscopic particles both organic and inorganic. While no single method is applicable to every sample, particularly when working with mixtures or a complex sample matrix, a suite of microchemical methods, combined with precise sample preparation and experienced interpretation, can provide a wealth of information from unknown organic particles less than 10 micrometers in size.

What in the (Microscopical) World?

Without the scale bar, you might think this was a photograph of the newest fruity pebble cereal being marketed to young children during Saturday morning cartoons. It isn’t. The presence of the scale bars attests to the fact that it is an altogether different, and perhaps more interesting subject. These particles were collected from the interior of a color laser printer.

Mislabeled Products: Tattoo Inks

Do the contents of a product actually match its label? Does a formulation contain undeclared ingredients? In one instance, tattoo inks were submitted to Microtrace for characterization of their pigment composition. Confocal Raman spectroscopy assisted by microscopical observations helped to identify the pigments in these inks. Read More
