REM-EDX, this abbreviation says a lot! It stands for a new test method, the "raster electron microscopic analysis by means of energy-dispersive micro range analysis". The process precisely determines the elemental composition of particles. Based on the results of the determined metal alloys, inferences can be made with regard to certain components from which particles with a size of only a few micrometres originate. Thus, the REM-EDX analysis provides the perfect support when searching for machine elements with signs of wear or determining contaminations in the form of solids. The analyses are performed by Industrieanlagen-Betriebsgesellschaft mbH (IABG) in Ottobrunn near Munich. OELCHECK’s cooperation partner has the necessary high-tech equipment and well-founded expertise for examining and assessing complex damage incidents. OELCHECK separates the particles that are to be analysed from the oil samples, provides background information and assists with the diagnosis of analysis results. Metallic abrasion quickly intrudes into oil or grease if wear or contamination particles attack lubricated machine components. OELCHECK already detects even the smallest particles in oil samples in the initial stages of the wear process. Atomic emission spectroscopy (AES) detects up to 30 elements that make up the particles. However, this analysis reaches its limits when dealing with particles that are larger than 5 μm. The exact composition and origin of larger particles or hard residue found in filters, oil samples or waste oil can often be clarified with an REM-EDX analysis.
