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.

Frequently Asked Questions about eraoil
We recommend a preventive maintenance schedule every 6 months according to the user manual. Every 24 months, a complete service should be performed by a qualified technician or the eralytics support team to ensure long-term instrument precision reliability. Regular maintenance is essential for ensuring the high performance of your equipment. While basic preventive steps can be managed internally on a 6-month cycle, the 24-month interval is a deep-dive service conducted by experts. These procedures ensure your device remains compliant with industry standards and continues to deliver reliable results.
Key maintenance activities include:
– Comprehensive visual inspections of all specified components
– Installation of the latest software updates to improve functionality
– Execution of the Initial Qualification Test (IQT) for verification
– Replacement of wear-and-tear parts by certified personnel

eraoil measures various liquid samples with a viscosity up to 2500 mm²/s at anbient conditions and a flash point above 50°C. For accurate results, particles should not be bigger than 10 μm. To ensure the highest precision, samples should meet specific physical criteria. High viscosity or large particulate matter can interfere with the sample’s transport to the spark, leading to under-reported elemental concentrations.
Key limitations and preparation requirements include:
– Particle size: Particles over 10 μm may not be effectively vaporized by the rotating disc electrode
– Viscosity: The system supports liquids up to 2500 mm²/s @ 20°C. Samples exceeding this limit must be diluted before testing
– Flash point: For safety and performance, samples with a flash point below 50°C require dilution
eraoil is designed exclusively for liquid sample analysis to ensure consistent electrode contact. If you need more information, please contact our service and support team >>
The instrument comes already factory calibrated and does not require further calibration by the user. However, operators have to perform regular validation checks to ensure precision which may lead to a required standardization. Validation check is essintial for reliable elemental analysis. We recommend using the “V26-100” standard, though other CRMs are compatible. Following ASTM D6595 guidelines ensures your data remains accurate throughout operation.
This may happen over time due to drifts in electronic components, but mainly due to changes in the environmental conditions. Perform a validation check to confirm performance. If any measured element deviates by more than ±10% from its reference value, the check has failed. In this case, a standardization is required to counteract drift and restore accuracy. If your results fall outside this range, follow these steps:
– Consult the manual: Detailed step-by-step instructions for the standardization procedure are available in your eraoil user manual
– Inspect hardware: Check the lens and spark stand for cleanliness, as residue can cause significant measurement offsets
– Verify standards: Ensure that your “V26” or other CRM standards are not expired or contaminated
– Run a standardization: This process adjusts the instrument’s response to re-align with the original factory calibration
By maintaining these measures, it is guaranteed that your eraoil analysis remains compliant with ASTM D6595. If you need more information, please contact our service and support team >>
Maintain your device through regular cleaning: wipe the disc and sample cup holders before every test, empty the sharpener drawer if required, and perform a deep clean of the lens and sample chamber at least once a month. Preventing sample carryover and graphite dust accumulation ensures the optical path remains clear and the electronics stay protected. Don’t use aggressive chemicals on painted housing surfaces. If you need more information concerning cleaning, please contact our service and support team >>
eraoil includes an integrated ventilation system to safely vent exhaust gases and a door-interlock safety mechanism. This ensures that the high-energy spark only activates when the chamber is sealed, protecting the operator at all times. Designed for demanding laboratory and field environments, the eraoil prioritizes both user safety and atmospheric integrity. Because the analysis involves vaporizing approximately 0.5 mL of oil per test, managing the resulting combustion byproducts is critical.
Key safety components include:
– Built-in ventilation: An internal extraction system captures exhaust gases generated during the spark process and directs them through a dedicated outlet at the rear of the device for external venting
– Spark interlock system: To prevent accidental exposure to high-voltage discharge, the instrument features an electronic sensor. The spark will not generate if the door is open; if opened during a measurement, the spark terminates instantly. If you need more information, please contact our service and support team >>
