Authors Jonah Kirkwood † and Mustafa Kansiz* Agilent Technologies † Mississauga, ON, Canada * Melbourne, Australia Identifi cation of contaminants in vehicle fuel tank caps using FTIR ATRmicroscopy Application note Materials testing and research Introduction Manufacturers of parts and components to the automotive industry are required to assure the quality of their products, and FTIR spectroscopy is widely used for this purpose. In this example, it was apparent that fuel tank caps were being contaminated by an unknown material during production. The contaminants were ~20–300 µm in size. As the unknown particles were small in size, an FTIR microspectroscopy technique was used to investigate.
Experimental Instrumentation To perform the analysis of micron-sized contaminants, an Agilent Cary 660 FTIR spectrometer coupled to a Cary 610 FTIR microscope was employed. In order to facilitate direct measurement of the contaminated regions, without any sample preparation, a ‘slide-on’ germanium micro attenuated total refl ectance (ATR) accessory was used. The system enables fast, sensitive and precise microscale direct measurements. The accessory is also available with an optional diamond crystal for the analysis of very hard materials. Sample analysis Minimal sample preparation was required for the analysis. The contaminated regions were simply cut out and placed on a glass slide, which was placed on ATR the sample stage of the Cary 610 FTIR microscope coupled to a Cary 660 FTIR spectrometer. The system was confi gured with standard mid-IR components (mid-IR source, KBr beamsplitter, 250 micron narrow band MCT microscope detector) with data collected at 4 cm -1 spectral resolution with 32 co-added scans (10 seconds). Results and discussion A section of the fuel tank cap (distinctive yellow in color) that was free from contamination was sampled by placing the ATR directly onto the sample surface. High quality spectra were acquired in 10 seconds. The contaminants (red specks) were visibly distinct from the fuel cap, so data was collected from the center of one of these sections. The resulting spectra are shown in Figure 1. Figure 1. ATR-FTIR analysis of a fuel tank cap. Top: Spectrum measured in a clean section; Bottom: Spectrum measured of a contaminated section 2
