Page 1 of 2 Trace Contaminants an TON Co AIRED Detection & Identification of Trace Contaminants in Finished Products and Chemical Formulations EREIN IS UNCLASSIFI DATE L2-l0-2005 BY 6 ED O324 UC BAW SRS / LSC 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 tow 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. Trace Contaminant & Residue Analysis - Cost Range Volatile & Semivolatile Contaminants Determined by heated head space sampling followed by GC/MS analysis - $100 - 300 Surface Contaminants Surface residues which cause poor coating adhesion or bad electrical contact are solvent extracted and analyzed by micro FT-IR spectroscopy. - $150 - 300 Trace Metal Impurities Determined by an ashing of the sample followed by acid digestion and atomic spectroscopy analysis - $70 - 150 Home - Directory - Polymers - Rubbers - Paints - Pharmaceuticals Trace Contaminants - Compositions - Forensic - Failure Analysis ‘http://www.therightstuff.com/trace.html 5/6/2005
