Inorganic Testing

Environmental wet chemistry testing is how we got our start back in 1982. We have come a long way since then, but our general chemistry testing is still the backbone of our company. Few environmental labs have our extensive capabilities when it comes to wet chemistry testing. Teklab, Inc is a NELAC Accredited Environmental Testing Laboratory that provides testing for wet chemistry constituents as required by various regulatory authorities. A listing of our testing methods is shown below. We recommend that you use a NELAP accredited Environmental Testing Laboratory whether your application requires it or not.
