GNR S.r.l.
Measuring instruments
Company Overview and History
G.N.R. s.r.l., established in Milan, Italy, in 1984 by Mario Gungui and Antonio Nigro, has grown into a global producer of advanced analytical instruments. The company's foundation involved taking over OPTICA srl, an early European pioneer in analytical instrumentation. In 2004, GNR diversified its portfolio by acquiring ItalStructures srl, a company founded in 1966 specializing in X-Ray Analytical Instruments. With over 40 years of experience, GNR operates its head office and production site in Agrate Conturbia (NO), Italy, and maintains a worldwide presence through an extensive sales and support network. The company is committed to continuous improvement, evidenced by its ISO 9001 certification and significant annual investment in research and development, often in collaboration with leading university departments.
Advanced Analytical Solutions
GNR offers a comprehensive range of 'MADE IN ITALY' analytical instruments designed for diverse industrial and research applications. Its core offerings include Optical Emission Spectrometers (OES) such as the compact S1 MiniLab 150 and S3 MiniLab 300, and the advanced S6 SIRIUS 500, which are crucial for rapid and accurate elemental analysis of metal alloys, including challenging matrices and trace elements. For in-service oil analysis, GNR provides Rotating Disc Electrode Optical Emission Spectrometers (RDE-OES) like the RotrOil series, compliant with ASTM standards, capable of analyzing wear metals, contaminants, and additives in lubricants without extensive sample preparation.
The company's X-Ray portfolio features X-Ray Diffractometers (XRD) like the AreX D benchtop unit for precise retained austenite determination in steel (ASTM E 975-03 compliant), and the Explorer for material characterization, phase analysis, and thin film studies. GNR also supplies X-Ray Fluorescence (XRF) instruments, including Energy-Dispersive XRF (ED-XRF) and Total Reflection XRF (TXRF), which are utilized for elemental analysis, trace element quantification, and non-destructive testing across various materials and industries. Complementing these instruments, GNR manufactures sample preparation machines, including electrogrinding and lapping machines, essential for optimal spectrometer performance.
Industry Applications and Expertise
GNR's analytical instruments serve a broad spectrum of industries, including metallurgy (foundries, steelworks), automotive, aerospace, chemical, petrochemical, pharmaceutical, environmental, and forensic sectors. Their solutions support critical processes such as raw material quality control, production monitoring, Positive Material Identification (PMI), research and development, and condition-based maintenance. The company’s focus on precision, speed, and reliability positions it as a key partner for organizations requiring robust and accurate material analysis. GNR’s proprietary software, such as EOS® for OES and Austenite for XRD, enhances usability and functionality, providing comprehensive control and data management.
