Detection & Identification of Trace Contaminants in Finished
Products and Chemical Formulations
This laboratory has devised many unique methods to detect and isolate trace impurities in
finished products such as micro circuitry and a variety of other products where trace impurities
interfere with the products function. An example of this would be a very thin film of oil residue
on the surfaces of micro switch contacts which prevents good electrical contact. We have the
ability to identify these residues and help the client determine their source.
Chemical formulations are often found to contain low levels of impurities which render them
unacceptable for use. A glass cleaner, for example, may leave an oily residue or a scouring
compound may contain low levels of an abrasive chemical which can scratch or mar a
porcelain surface.
We can determine trace amounts of specific fuels in soils, water or any material. Further, if a
fuel contains a small amount of contaminant we will identify it and specify its content.
