Oil Analysis Machines for Lubricants and Maintenance

The practice of used oil analysis started more than a century ago on locomotive engines. Today, thanks to increasingly advanced oil analysis machines for lubricants, it has become a key lever to prevent failures, reduce unplanned downtime, and optimize operating costs.

It is now one of the most important components of condition-based maintenance (CBM)—a practice that assesses a machine’s condition by periodically collecting data on key health indicators in order to define maintenance schedules. In this scenario, having dedicated oil analysis machines for maintenance makes it possible to turn oil data into fast, targeted operational decisions.

Lubricating oil is the lifeblood of oil-wetted machinery. In-service oil analysis can provide information on:

• machine wear conditions
• lubricant contamination
• lubricant condition over time

In particular, elemental analysis remains the core technology in oil analysis because it enables effective detection of wear metals and contaminants, supporting periodic checks and interventions before critical issues occur.

GNR’s RotrOil product line is the leading solution for the rotating disc electrode (RDE-OES) method, which is the preferred approach for oil analysis when fast testing with no sample preparation is required. This is especially useful when you need to speed up lab routines or when analysis must be carried out in operational environments where simplicity and short turnaround times make the difference.

RotrOil complies with:

• ASTM D6595 standard test method for determining wear metals and contaminants in used lubricating oils or used hydraulic fluids by rotating disc electrode atomic emission spectrometry
• ASTM D6728 standard test method for determining contaminants in gas turbine and diesel engine fuels by rotating disc electrode atomic emission spectrometry

Below are the GNR machines available for lubricant oil analysis and maintenance processes:

• R4 RotrOil Automated
  R4 to automate the oil analysis process and minimize costs in your laboratory
• RotrOil – Rotrode Emission Spectrometry
  The latest generation and most advanced version of the traditional Rotrode emission spectrometer—the perfect instrument for the oil analysis laboratory. Thanks to its new compact design, it is a very robust and reliable unit that can be moved and transported to different locations where analysis needs to be performed.
