Technical Services
GTI is poised to serve as your testing partner. With a history of more than seven decades of analysis and developing solutions for the natural gas industry – and state-of-the-art laboratories, test facilities, and equipment at our Illinois headquarters and across the country – we are your single source for the performance of both standardized and custom tests.
Materials and Analytical Testing
Materials and Analytical Testing
Our laboratory, accredited by the American Association for Laboratory Accreditation (A2LA), is in compliance with ISO/IEC 17025 on certificate 2139.01 and 2139-04. It specializes in performing ASTM and ISO tests, as well as customized analysis of metals, plastics, and composite materials for the natural gas, power generation, water and other industries.
Chemical Research Services
For more than 40 years, GTI has been providing a wide range of energy measurement services unavailable in most commercial laboratories. They are used by energy companies and others to characterize a variety of materials, ensure efficient operation of gas-measuring equipment, and help improve the quality of the products they sell. We provide complete laboratory services for natural gas, biogenically derived gas, coal, liquid fuels, and other materials for the natural gas and power generation industries. Work is performed in a laboratory accredited by A2LA in compliance with ISO/IEC 17025 on certificate 2139.01 and 2139-04.
GTI also received accreditation for three new tests for liquid hydrocarbon analysis in 2014. These new test methods are: ASTM D664 (for acid number of petroleum products by potentiometric titration), ASTM D5291 (for instrumentation determination of carbon, hydrogen, and nitrogen in petroleum products and lubricants), and ASTM D5622 (for determination of total oxygen in gasoline and methanol fuels by reductive pyrolysis). Currently, these tests are supporting the work being done at GTI to advance the patented IH2® technology—a catalytic thermochemical process that provides a cost-effective route to producing liquid transportation fuels from renewable sources.
Microbially Influenced Corrosion Testing
GTI offers a microbially influenced corrosion (MIC) testing service that directly detects and quantifies (without prior growth) corrosion-causing microorganisms typically found in pipes, production wells, and other equipment used by the natural gas, petroleum, chemical, water, produced water and wastewater industries.
GTI Testing Laboratories is one of only a few laboratories in the world that offers DNA testing for corrosion-causing microbial populations and is the first U.S. lab to receive A2LA accreditation for microbial corrosion testing services. qPCR is a molecular biological method used to quantify the total number of microbial organisms responsible for microbial-influenced corrosion (MIC) from liquid, gas, and solid samples. Among the organisms targeted by GTI’s qPCR testing are total bacteria, total archaea, sulfate-reducing bacteria, sulfate-reducing archaea, acid-producing bacteria (acetic and butyric acid producers), iron-oxidizing bacteria, denitrifying bacteria, and methanogens. GTI also offers biodiversity analyses, live dead analysis, spore tests, sampling manifolds and more.
Environmental and Forensics Testing
Our environmental forensic tools and trace environmental analyses can be leveraged to identify contaminants in air, water, soil, and sediment.
