G.N.R. S.r.l.

With 30 years of technological experience, GNR is a worldwide market producer of advanced X-ray (XRD, XRF) and Optical Emission Spectrometer (OES) systems for complete solutions in structural and elemental analysis with thousands of machines installed and operative all over the world.
GNR OES Product Line
Optical Emission Spectrometry (OES) is an analytical technique, universally considered and used to determine the chemical composition of metal alloys.
Thanks to the method precision and the short analysis time, it represents a valid control system of production in all the fields regarding metal industry (primary alloys foundries, metal processing industries, mechanical industry) in any time during production cycle, in the case it is necessary to have a fast and accurate chemical analysis of material.
GNR Spark Optical Emission Spectrometers are the perfect instruments for Metal Analysis and we offer different models depending on analytical needs, from mobile and portable equipment (Esaport) to benchtop lab spectrometer (Minilab and Metal Lab Plus) till top-laboratory solution (Atlantis).
OES technique is also used with Rotroil model for predictive maintenance in Oil analysis , rapid determination of wear metals contaminants ,additives in lubricants, Hydraulics fluids, coolants.
GNR X-Ray Product Line
X-Ray Diffraction (XRD) is a non-destructive technique for the qualitative and quantitative analysis of the crystalline materials, in form of powder or solid.
GNR has developed, in cooperation with academic and industrial users, a set of technically advanced and flexible diffractometers able to satisfy different level of requirements and different operating budget.
GNR XRD Product Portfolio covers a huge range of applications for materials characterization and quality control of crystalline or non-crystalline materials such as powders, specimens, thin films or liquids.
Residual Stress could be induced by machining, grinding, rolling, deep drawing, welding, thermal hardening and shot peening; its quantification allows to prevent fatigue damage and to control material's durability and safety.
StressX provides a flexible solution to residual stress determination on samples of any dimensions by the original synergy between compact X ray diffractometer and 6-axis robot.
Accurate measurement of the retained austenite levels is important in the development and control of heat treatment process in steel industry.
Thanks to AreX innovative concept, Retained Austenite volume percentage can be measured in few minutes, just placing the sample and pressing start button. Typical Measuring time is 180 seconds.
