Rapid High-Throughput Species Identification Of Botanical Material Using Direct Analysis In Real Time High Resolution Mass Spectrometry, Rabi A. Musah, Ashton D. Lesiak

Chemistry Department Faculty Scholarship

We demonstrate that direct analysis in real time-high resolution mass spectrometry can be used to produce mass spectral profiles of botanical material, and that these chemical fingerprints can be used for plant species identification. The mass spectral data can be acquired rapidly and in a high throughput manner without the need for sample extraction, derivatization or pH adjustment steps. The use of this technique bypasses challenges presented by more conventional techniques including lengthy chromatography analysis times and resource intensive methods. The high throughput capabilities of the direct analysis in real time-high resolution mass spectrometry protocol, coupled with multivariate statistical analysis …
