eraspec oil X

The world’s smallest FTIR analyzer for outstanding lube oil analysis

The eraspec oil X is an advanced Fourier Transform Infrared (FTIR) spectroscopic analyzer designed for the comprehensive monitoring of lubricant condition with extended analytical coverage. Built on eralytics patented mid-FTIR interferometer with laser- and temperature-controlled design, the eraspec oil X provides laboratory-grade measurement performance in a lightweight and rugged metal housing suitable for industrial, laboratory and field use. The measurement itself is fully automated and requires only 2 mL of sample with syringe filling. In less than two minutes eraspec oil X delivers a detailed fingerprint of lubricating oils with highest precision.

eraspec oil X complies with major international standards, including ASTM, DIN and JOAP. This ensures consistent and traceable analysis of lubricant degradation, contamination and additive depletion. The instrument uses an optimized dual-position 100 µm transmission cell with automated reference measurement to facilitate solvent-free operation while maintaining high repeatability and spectral accuracy.

In addition to standard FTIR oil condition parameters, eraspec oil X provides extended spectral evaluation capabilities, allowing improved sensitivity to oxidation, nitration, sulfation, fuel dilution, water, glycol, soot, and additive chemistry. Two complementary analysis modes are supported: Direct Trending, which evaluates condition parameters directly from absorbance values; and spectral subtraction, which compares in-service oil spectra with fresh-oil references to isolate chemically relevant changes. This dual workflow supports precise monitoring across a broad range of lubricant formulations and operating environments.
