Abstract
The present disclosure describes methods and systems that combine Raman spectroscopy performed in a manner that utilizes one or more of widefield illumination, simultaneous multipoint Raman spectral acquisition, and spectral unmixing for the purpose of high throughput polymorph screening. Features of this methodology include: (a) high throughput polymorph screening to reduce crystal orientation effects on Raman spectra; (b) in-well multi-polymorph screening using increased statistical sampling; and (c) multipoint spectral sampling to enable spectral unmixing.
