Chemistry Services

GT Engineering maintains a comprehensive analytical chemistry laboratory specializing in polymer and plastics analysis. Capabilities include a broad spectrum of sampling and analytical methods for inorganic and organic materials of industrial and environmental origin.

Our goal is to deliver relevant, accurate, and cost-effective results to our clients.

Expert Services


Forensic Engineering

The application of engineering principles to the investigation of materials, products, structures, components, or processes that fail, causing injury or property damage.

Failure Analysis

The process of collecting and analyzing data to determine the cause of a failure, frequently with the goal of determining corrective actions.

Reverse Engineering

The process of analyzing a product to extract design information for the purpose of reproducing or improving the product.

Patent Litigation Support

The application of engineering principles in support of litigation concerning patent infringement, defense, or patentability.

A Closer Look


Analytical Chemistry

GT Engineering is equipped to perform a number of standardized tests using methods such as those identified in ASTM and EPA protocols. We also conduct research and design of test methods tailored to the specific needs and goals of our clients.

Our in-house instrumentation capabilities include Fourier Transform Infrared Spectrometry (FTIR) coupled to microscope and Attenuated Total Reflectance (ATR) sampling systems, Differential Scanning Calorimetry (DSC), High Performance Liquid Chromatography (HPLC) coupled with UV-VIS and Refractive Index (RI) detection systems, Gas Chromatography with Flame Ionization Detection (GC/FID), and automated mercury analyzer using atomic fluorescence spectroscopy. Our capabilities are extended by strategic alliances with a number of universities and other laboratory and research facilities.

Polymer Analysis

A wide variety of polymeric materials including plastics, rubbers, and adhesives have been the subject of forensic investigations at GT Engineering. Plastics investigations have included PVC, CPVC, PE, PP, PC, nylons, acetals, etc. used in a wide range of piping, commercial plumbing, and consumer goods (including fibers and woven products, medical instruments). Rubbers and polymeric materials used as gasket materials, e.g. nitrile, EPDM, butyl rubber, etc. are routinely involved in our investigations. Our in-house chemistry laboratory is specifically equipped to diagnose polymeric issues with instrumentation including DSC, microscopic FTIR, HPLC and GC as well as environmental exposure chambers. Issues we have dealt with include ultraviolet degradation, contact with incompatible solvents, oils and chemicals leading to dissolution or stress corrosion cracking, paint interactions, auto-ignition of batteries, and contamination from fires. We have had major litigation cases dealing with issues of plastics formulation and manufacturing processes and have been retained by manufacturers to assess products in their design stage.

Forensic Engineering

GT Engineering has vast experience providing technical support to clients in legal cases. These matters often involve accident site investigations, mechanical, chemical and materials analyses of products and processes, review and interpretation of codes and standards, and technical reporting. We have served as expert witnesses in court providing unbiased and scientifically sound opinions in numerous cases involving product failure, industrial accidents, materials evaluation, structural failure, accident reconstruction, fires, and explosions.

Reverse Engineering

There are many uses for reverse engineering analysis from determining how to improve an existing product to recreating a product no longer available to analyzing a competitor’s product for comparison. GT Engineering has the capabilities to determine how a component mechanically functions, what it is made from, the mechanical properties of the component, and how it was manufactured. We can also analyze the stresses in the component to determine likely failure modes and locations as well as the design limitations. We can offer advice on improving the strength and durability of a component as well as offering alternative materials and manufacturing methods.
