FTIR fingerprinting of lube oils
eraspec oil X is the perfect solution for FTIR fingerprinting of lubricating oils, providing a comprehensive composition of any lubricant or base oil. Monitoring oil degradation like oxidation, screening contaminants such as water, and checking levels of antioxidant additives was never easier. The FTIR spectra are saved on the analyzer and can be easily exported for further use.

Portable and easy lube oil analysis
eraspec oil X is a lab-grade FTIR spectrometer built inside a lightweight and rugged metal housing making it ideal for on-site lubricating oil analysis. Whether you are testing fresh or used oil, eraspec oil X provides fast and reliable results in the lab as well as in the field. eraspec oil X is factory calibrated and comes with a built-in reference cell that allows for fully automated reference measurements. The measurement itself is fully automated and requires only 2 mL of sample. In less than two minutes eraspec oil X delivers a detailed fingerprint of lubricating oils with highest precision.

Analysis of fresh and used oils
With its modular design the detailed analysis of fresh oils and used oils becomes a simple and straight-forward routine. Important degradation parameters such as oxidation, nitration or sulfation as well as soot or fuel dilution are readily monitored by IR spectroscopy. Additionally, it comes pre-programmed for important antioxidant and wear additives. Evaluation is done according to latest ASTM and DIN standards like ASTM E2412, ASTM D7624 and many more. Both direct trending and spectral subtraction incorporating the fresh oil spectra are readily possible.

eraspec oil X – fast & accurate oil condition monitoring
As part of eralab OCM, eraspec oil X also provides fast & accurate oil condition analysis to support predictive maintenance for
- Contamination detection: Detects contaminants like water, glycol, fuel, or other impurities compromising oil quality
- Oil composition monitoring: Measures oxidation, nitration and sulfation
- Additive depletion: tracks levels of antioxidants and anti-wear additives

Measurement procedure
eraspec oil X performs spectral FTIR analysis of lubricants in three easy steps:
- Enter the sample ID, select the oil type and the method
- Fill the sample with a syringe from the top of the analyzer into the measurement cell
- Press the RUN button
The measurement steps are visualized on the display, showing the deflection of the moving mirror of the interferometer. When the measurement is completed the results are displayed and can be printed or exported with a single click.
