title: Fourier-transform infrared imaging using a rapid-scan spectrometer.
abstract: We present a major improvement to the Fourier-transform infrared (FTIR) imaging technique brought about by replacement of the commonly used step-scan spectrometer with a rapid-scanning spectrometer. This advancement dramatically decreases the time required for data collection without decreasing the data quality. With this new instrumental setup, an imaging data set consisting of 64x64 spectra with a 4-cm (-1) spectral resolution over a 1360-cm (-1) spectral range can be collected in 34 s. As a practical example, we demonstrate what we believe to be the first application of FTIR imaging to the screening of adsorbates on the elements of a combinatorial library containing different supported catalyst materials in the same reactant feed.
