GNR Analytical Instruments
Spark optical emission spectrometers for metal analysis — plus oil analysis, sample preparation, XRD and TXRF from Italy.
About GNR
GNR Analytical Instruments (G.N.R. s.r.l., Agrate Conturbia, Italy) designs and manufactures analytical instruments for metal analysis and material characterisation, with around 40 years of experience in the field.
Spark optical emission spectrometry (OES) is the core of the portfolio: laboratory, ultra-compact and portable spectrometers that determine the elemental composition of ferrous and non-ferrous alloys for foundries, steel producers and metalworking plants.
Alongside OES, GNR builds rotating disc electrode spectrometers for used-oil analysis, automatic sample-preparation grinders, X-ray diffractometers for phase analysis, residual stress and retained austenite, and total-reflection X-ray fluorescence (TXRF) spectrometers for trace-element analysis.

Why EMUS represents GNR
Spark OES results depend on the analytical programs, matrices and calibration standards configured for your alloys — not on a catalogue headline. EMUS works with laboratories and foundries in the Balkan region to define which matrices and elements must be covered, which GNR model and configuration fits the throughput, and how samples will be prepared, then supports installation, training and calibration.
- Spark OES from ultra-compact and portable units to top-range laboratory systems.
- Configurations matched to your matrices, elements and analytical ranges.
- Sample preparation and OES selected together for repeatable results.
- Oil analysis, XRD and TXRF from the same manufacturer, without mixing techniques.
