Lyza 7000 Used Oil Package (FTIR In-Service Oil Analysis)

Significance of the Topic

Oil condition monitoring is crucial to ensure reliable machinery performance and extend equipment lifespan. Fourier transform infrared (FTIR) spectroscopy enables rapid, non-destructive assessment of lubricant degradation and contamination, supporting predictive maintenance strategies and reducing unplanned downtime.

Objectives and Study Overview

This application note describes the capabilities of the Anton Paar Lyza 7000 benchtop FTIR spectrometer for in-service oil analysis. It aims to demonstrate compliance with key ASTM standards, illustrate a guided workflow, and highlight system efficiency in both laboratory and field environments.

Methodology and Instrumentation

The Lyza 7000 uses a transmission cell and a pyroelectric DLaTGS detector to record absorbance spectra from 350 to 7 500 cm⁻¹. Analysis methods preconfigured to ASTM protocols quantify oxidation, nitration, sulfate by-products, antiwear additives (ZDDP), water, fuels, glycols, and soot. Users can customize calibration libraries and pass/fail criteria within the embedded touchscreen software, eliminating the need for an external PC.

Used Instrumentation

• FTIR Spectrometer: Lyza 7000 with pyroelectric DLaTGS detector
• Optics: Gold-coated mirrors, KBr windows, sealed aluminum housing
• Spectral range: 350–7 500 cm⁻¹; resolution 1.4–16 cm⁻¹
• Signal-to-noise ratio: 55 000 : 1 (1 min, 8 cm⁻¹, 1 900–2 250 cm⁻¹)
• Interferometer: Permanently aligned cube-corner design
• Features: 10.1” PCAP touchscreen, humidity sensor with alert, molecular sieve desiccant
• Compliance: ASTM E2412, D7214, D7412, D7414, D7415, D7418, D7624, D7844

Main Findings and Discussion

The system completes a full oil condition scan in under 30 seconds, enabling high sample throughput. The guided workflow and intuitive interface allow untrained personnel to perform reliable pass/fail analyses. Compact design frees bench space by integrating data processing on the instrument, while health monitoring features ensure measurement consistency.

Benefits and Practical Applications

• Rapid detection of lubricant degradation and contaminants
• Standards-compliant methods ensure data reliability

Future Trends and Potential Applications

Emerging AI-driven spectral interpretation and expanded calibration databases will further streamline oil analysis. Integration with IoT platforms could enable real-time condition monitoring and remote diagnostics. Miniaturized FTIR modules may extend in-situ analysis capabilities to service vehicles and production lines.

Conclusion

The Anton Paar Lyza 7000 FTIR spectrometer provides a robust, standards-compliant solution for in-service oil analysis. Its speed, ease of use, and flexible workflow support both laboratory and on-site maintenance programs, enhancing asset reliability and reducing operational costs.
