Optical Emission Spectrometry

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.

X-Ray Fluorescence

TXRF is founded on the same principles of the EDXRF with, however, one significant difference. In contrast to EDXRF, where the primary beam strikes the sample at an angle of 45°, TXRF uses a glancing angle of a few milliradians.

Owing to this grazing incidence, the primary beam is totally reflected. By illuminating the sample with a beam that is being totally reflected, absorption of the beam in the supporting substrate is largely avoided and the associated scattering is greatly reduced. This also reduces the background noise substantially.

A further contribution to the reduction of the background noise is obtained by minimising the thickness of the sample. A small drop of the sample (5-100 microliters of the substance dissolved in an appropriate solvent) is placed on a silica carrier. On evaporation of the solvent a thin film, a few nanometers thick, remains. 

In practice the greater part of the scattering normally arising from the sample and its matrix is eliminated. This is because matrix effect cannot build up within minute residues or thin layers of a sample. Besides its high detection power, simplified quantitative analysis is made possible by an internal standard.

R3 RotrOil

R3 RotrOil spectrometer instrument is a compact, transportable and easy to use optical emission spectrometer designed specifically to determine trace concentration in wear metals, polluting materials and additives in lubricating oils, transmission and refrigerating liquids.

R3 RotrOil spectrometer is complaint to the requirements of the ASTM D6595-00 Standard Test Method for determination of Wear Metals and Contaminants in used lubricating oils or used hydraulical fluids by Rotating Disc Electrode Atomic Emission spectrometry. 

R3 RotrOil Instrument is available in two different versions, the first one is the more compact one (as showed in the picture on the right), the second one is with PC included with touch screen management, in general preferred in the Military domain (picture available in the brochure enclosed in the Download Section).
