Infrared Material Component Analysis Corroboration by X-ray Diffraction
EMSL Project ID
60281
Abstract
This project aims to build a spectral library which links both structural and spectroscopic data. To obtain the structural information, we require diffraction data from a range of samples for which we have measured the infrared spectra. Infrared (IR) spectroscopy is a common technique for rapidly analyzing mixtures due to its specificity, but it is well-complemented by X-ray diffraction (XRD) which provides high accuracy in determining mixture constituent identity and ease of data deconvolution. Our intention is to create spectral libraries that have sample-matched reflectance spectra (600-33,000 cm-1) and XRD data of specified minerals and compounds that sponsors can use for complex mixture analysis in the field. We have approximately 100 samples for which we require XRD data. EMSL’s currently powder diffractometer is equipped with a 10-position sample changer, and so we will be able to collect the required diffraction patterns in a relatively small number of overnight runs.
