WELCOME to G&T Analytical Services
A DIVISION OF VPREP
G&T Analytical Services specialize in remote and on-site comprehensive training and application troubleshooting for XRF (X-ray fluorescence) and OES (spark optical emission) instrumentation. While training is our goal, we recognize that analysts have increasingly multifunctional roles limiting the time to specialize in one instrument or technique. As a result, we can also help to develop and customize quantitative methods to help customers achieve their analytical needs. We are happy to travel to you and train in the comfort of your own facility or assist remotely. The company is dedicated to rigorous educational programs ensuring that professionals are proficient in the use of XRF and OES technology for accurate material analyses. Our services are designed to enhance the expertise of operators and uphold the highest levels of quality and safety for all your application needs.
