eraoil

The stand-alone RDE-OES spectrometer.

eraoil is the first and most advanced stand-alone rotating disc electrode spectrometer analyzing wear metals, additives, and contaminants in all kinds of operating liquids, like lubricating oils, heavy fuel oil, fuels, coolants, process water, etc. Up to 32 elements are measured fully automatically within 30 seconds. eraoil’s high-end CMOS detector in combination with the automatic background correction allow for a sub-ppm detection limit (LOD) for most elements.

Smallest footprint with built-in PC

eraoil’s unique stand-alone design offers a rugged all-in-one package for operation even in the smallest on-site testing labs. It comes with a built-in 10” color touchscreen and a PC. Even an electrode sharpener and an automatic ventilation system are integrated into the eraoil. Still, it is the RDE-OES analyzer with the smallest footprint on the market. eraoil is very easy to use even for untrained operators. The automated measuring procedure follows simple steps and is therefore perfect for on-site inspection: Just fill the sample cup, close the door, and push the start button. The elemental concentration is available immediately.

High-precision oil and fuel analysis

eraoil is fully compliant with ASTM D6595 (oil) and ASTM D6728 (fuel). ASTM D6595 is the standard for identifying wear metals and contaminants in used lubricating oils and used hydraulic fluids by rotating disc electrode optical emission spectrometry. For determinating contaminants in gas turbine and diesel engine fuel, ASTM D6728 is the standard of choice. To protect finished fuels against trace contamination eraoil is available with the special Low Detection Fuel Module to detect e.g. Potassium, Lithium, Sodium and Vanadium at LOD levels of as low as 0.1 ppm.

Applications for the spectrometer eraoil

Multi-elemental analysis is the core of in-service oil analysis. Thus eraoil is the perfect solution for wear metal analysis of lubricants from engines, transmissions, hydraulic systems and gears boxes. The fast and easy elemental analysis brings clear advantages for the operation of any commercial means of transport or machines in the industrial environment. This solution also offers clear added value for other applications such as coolants, metal working fluids, or any other process fluids.

Frequently Asked Questions

The eralytics eraoil analyzes up to 32 elements fully automatically in just 30 seconds. It is one of the fastest RDE-OES spectrometers for on-site used oil analysis. This high speed is achieved through advanced CMOS detector technology and automatic background correction. No sample preparation, such as dilution, is required, making it ideal for high-throughput OCM labs or maritime applications. Contact us if you need more information.

eralytics eraoil is fully compliant with ASTM D6595 (lubricants) and ASTM D6728 (fuel). It also shows excellent correlation with ICP methods according to ASTM D5185. Compliance ensures that results are accepted in regulated industries globally. It covers wear metals, additives, and contaminants. Documentation for ISO 9001 and CE standards is included as part of the technical package. Get more information on ASTM D6595 and D6728.

Maintenance is minimal due to the built-in electrode sharpener and automated ventilation system, which significantly reduces manual intervention. Because it requires no solvents, external cooling, or gases, operating costs (OPEX) are much lower than traditional ICP systems. Consumables like graphite electrodes can be replaced in seconds by the operator. Contact us if you need more information.
