Making your quality control of hydraulic and lube oils more efficient
Monitoring the quality of hydraulic and/or lube oils is critical to prevent premature wear of any kind of machinery. In this session we will look at this topic from a new perspective focusing on the combination of titration (potentiometric, thermometric, coulometric Karl Fischer titration) and Vis-Near-Infrared Spectroscopy (Vis-NIRS).
Combining titration (highly sensitive, specific, a widely used primary method) with Vis-NIRS (fast, non-destructive, results for multiple parameters at once) can make your oil condition monitoring and/or lubricant analysis much more efficient, especially, if your laboratory has to analyze large sample series every day.
Attending this session, you will learn and understand:
- The specific advantages of each method (titration and Vis-NIR-Spectroscopy)
- How and when to use these methods to measure critical chemical and physical parameters in lube and hydraulic oils
- What thermometric titration is and how it helps to improve robustness of serial acid number testing
- How to automate measurements of large sample series to increase efficiency and reproducibility
- How Vis-NIRS for lubricant analysis complies with ASTM guidelines and can save costs and time
Presenter: Robert Tobler (Application Specialist Titration)
