This document describes the analysis of silicon, tin, and titanium concentrations in jet-engine oil using spectrometric techniques, and the potential indications of component failure. It also mentions different analytical techniques and application areas.
The document discusses the importance of spectrometric oil analysis for detecting machine component failure by monitoring wear metal levels. It highlights limitations of conventional flame AAS and other techniques regarding particle size detection, particularly for particles larger than 5 microns.
The note specifically examines the capabilities of the Agilent GTA-96 graphite furnace AAS system for determining silicon, tin, and titanium in jet-engine oils. It provides detailed instrument parameters for both flame and furnace modes using the SpectrAA-40 spectrometer and outlines standard preparation and sample handling protocols.
