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. Our expertise spans several key areas of wet chemistry testing, including oxygen demands, nutrients, cyanide & phenol testing, solids, sulfur, physical testing, colorimetric metals, simple anions & halogens, and ionic characteristics. A detailed list of the specific tests we perform can be found below.

Comprehensive Analysis of Semi-volatile Organic Compounds

At Teklab, we specialize in the precise testing of a wide variety of Semi-volatile Organic Compounds (SVOCs) to meet the rigorous demands of industrial, municipal, and regulatory clients. Our advanced environmental laboratory routinely analyzes soils, waters, and special wastes using state-of-the-art methods, ensuring that every test we conduct is both accurate and reliable. From BNA and PAH testing to pesticides and herbicides, our comprehensive list of semi-volatile methods is designed to address your specific needs.

Understanding that many unique organic compounds exist, and local regulatory agencies may require testing beyond standard EPA or SW846 lists, Teklab performs validation studies to ensure your particular compound can be accurately extracted and analyzed. We pride ourselves on maintaining NELAP accreditation standards, providing you with trustworthy and legally defensible results. Whether your testing requirements are routine or specialized, Teklab’s commitment to quality and precision ensures that your environmental testing needs are met with the highest level of expertise.
