TEI® Chemical Testing

Established in 1965, TEI Analytical is an independent laboratory with a wide range of testing capabilities, from classical chemistry to state-of-the-art instrumental techniques. TEI® services help clients maintain effective quality control systems, document compliance with government regulations, and identify and correct errors early in the manufacturing process, saving both time and money.

TEI Analytical not only performs standard methods required for the Environmental Protection Agency, Nuclear Regulatory Agency, Food and Drug Administration, and other regulatory agencies, but also employs specialized techniques and methods tailored to the individual client’s needs.

Substances tested run the gamut from soil, air, water, food and pharmaceuticals, to inks, oils, adhesives, cosmetics, industrial wastes, metalworking fluids, and more. Tests identify and quantify heavy metals, trace elements, off odors, off flavors, moisture, calories, organic matter, corrosive agents, pesticide residues, PCBs, and other compounds. The lab also determines product formulations and quantifies food ingredients for nutrition labeling.

Consulting and R&D Services 

Unlike ordinary labs, TEI Analytical continues to serve the client after the test results come in. When test results indicate irregularities, experienced TEI staff consult with clients to identify and solve the problem. TEI® consulting services also include methods development for nonroutine analyses and research and development for six- to twelve-month projects.
