Bruker Avance III UltraStabilized 800 MHz Spectrometer

This system is housed in Schweitzer Hall. It has the latest and most advanced Ultra-Shield-Plus magnet with four radiofrequency (rf) channels, an ATM (automatic tuning and matching) and a TCI (1H/13C/15N) probe with cryo-chilled 1H and 13C preamplifiers.

Fig 1. (Below) Comparison of loading and score plots generated from preprocessed NMR spectra of EBC from 53 cats before (black) and after induction of early allergic asthma (red), using multivariate statistics. Panels A and D show PCA results. Panels B and E plot PLS-DA results. Panels C and F report multi-level PLS-DA results. Components 1 and 2 are plotted in the loading plots (A–C). Components 1, 2, and 3 are plotted in the score plots (D–F). Biomarkers that increased in the experimental asthma are labeled in red. A marker that decreased in the experimental asthma is labeled in blue. A peak too weak to be useful is labeled in gray.
