The spectra from the two sections of the fuel tank cap were overlaid using the Agilent Resolutions Pro software so that the data could be visually investigated to see the spectral differences (Figure 2). With just a few simple clicks, the software can subtract the two spectra to isolate the spectral contributions from the contaminant. The next step in the identifi cation process is to search the spectrum against a spectral database using either a custom-built or a commercially-available library. Figure 2. Result (purple) of subtracting the spectrum of a contaminated section (red) of the fuel tank cap from that of a non-contaminated section (yellow) One of the benefi ts of using a custom-built library is that it allows the analyst to search against their own proprietary data, at any time. It is also easy to create custom-built libraries, which can be useful for QA/ QC applications. However, commercial libraries can provide more advanced data-mining capabilities. The Resolutions Pro software provides direct access to the largest commercially-available FTIR libraries — including a signifi cant number of databases that are dedicated to polymer and materials applications. As a result of the library search (custom-built or commercial), the contamination was identifi ed to be from the wearing of a red plastic o-ring in a component of the machinery used during manufacturing. Conclusions The study has shown the Agilent Cary 660 FTIR with Cary 610 FTIR microscope fi tted with a micro- ATR accessory to be an excellent technique for the identifi cation of the source of contamination in polymeric materials (such as the fuel cap investigated in this instance). Data was collected in 10 seconds and the spectra were compared visually and subtracted to gain a better understanding of the contaminant. A commercially available spectral library search identifi ed the source of the contamination. 3
Authors Jonah Kirkwood † and Mustafa Kansiz* Agilent Technologies † Mississauga, ON, Canada * Melbourne, Australia Component failure analysis of vehicle spark plugs using FTIR spectroscopy with a micro-ATR large sample objective Application note Materials testing and research Introduction Preventing failure of components or identifying the cause of any failure quickly and reliably is vital across all industries in order to minimize downtime and save money. In this example, the spark plugs of a very large fl eet of commercial vehicles began to fail at an unacceptable rate soon after installation. Through simple visual observation, it was apparent that excessive deposits were accumulating on the spark plugs even after low mileage necessitating premature servicing and costly repairs. Clearly corrective measures needed to be implemented.
