Description
  

GTI’s Analytical Chemistry Laboratory gives the energy industry a depth of customized support unavailable in typical commercial laboratories. It provides complete laboratory services for natural gas, biogenically derived gas, coal, liquid fuels, and other materials for the natural gas and power generation industries, as well as for numerous municipalities and utilities. Our capabilities incorporate modern instrumental techniques and traditional referee methods providing highly accurate determinations. Advanced analytical capabilities include gas chromatography coupled with atomic emission and mass spectral detectors. 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). This laboratory is accredited by A2LA in compliance with ISO/IEC 17025 on certificate 2139-04.

  

This lab focuses on the fundamental properties and characteristics of materials. Forensic analysis of polymers, metals, and composites gives the ability to better understand failures before they become much larger problems. Standard and customized tests are conducted to determine density, thermal properties, tensile strength, compression, mechanical properties, and other characteristics. Advanced equipment such as scanning electron microscopy (SEM) is used for microstructural examinations and chemical composition determination. A temperature- and humidity-controlled room conditions specimens to ASTM specifications prior to testing. This laboratory is accredited by the American Association for Laboratory Accreditation (A2LA) in compliance with ISO/IEC 17025 on certificate 2139-01.

  

State-of-the-art microbiological research and testing services provided in this lab integrate molecular genetics techniques to areas such as pipeline microbial corrosion prevention and treatment, microbial characterization, molecular biology, and anaerobic digestion studies. Our microbial corrosion testing service uses quantitative polymerase chain reaction (qPCR) testing to directly detect and quantify (without prior growth) corrosion-causing microorganisms typically found in pipes, production wells, and other equipment. Our lab is one of only a few laboratories in the world that offers accredited DNA testing for microbial corrosion-causing microbe populations and is the first U.S. lab to receive A2LA accreditation for microbial corrosion testing services. This technique can be applied in the natural gas, petroleum, chemical, water, produced water and wastewater industries. Additional environmental capabilities are forensic chemical fingerprinting studies, including gas chromatography/isotopic ratio mass spectrometry (GC/IRMS), which measures stable isotope ratios of carbon to discriminate between different sources of carbon-containing contaminants.​
