Résumé : |
X-ray fluorescence (XRF) is a rapid, often nondestructive, elemental analysis technique that has been infrequently applied to crust and finished leather characterization. XRF can suffer from moisture and matrix effects, limiting its application in certain materials. The use of effective moisture management and homogenization can minimize these effects. An Oxford Instruments Twin-X benchtop XRF spectrometer, an Oxford MESA-5000 analytical XRF spectrometer and an AMTEC XRA CR 900 instrument were employed for qualitative and quantitative assessment of crust and finished leathers. Chromium calibrations to the "standard" ASTM method showed excellent accuracy and acceptable precision for both the Oxford Twin-X and the AMTEC instrument. Qualitatively, XRF can be performed to rapidly assess type of tannage and heavy metal contamination. Quantitatively, XRF can provide (for suitably-prepared samples) analytical figures of merit (accuracy and precision) that are competitive with conventional analysis techniques. |
