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.
