Chromatographic NMR in NMR solvents

Journal of Magnetic Resonance, 2008
Recently, it was demonstrated that pseudo-chromatographic NMR experiments could be performed using typical chromatographic solids and solvents. This first setup yielded improved separation of the spectral components of the NMR spectra of mixtures using PFG self-diffusion measurements.

Microscale NMR

Current Opinion in Chemical Biology, 2002
NMR spectroscopy is increasingly being used to characterize microliter and smaller-volume samples. Substances at picomole levels have been identified using NMR spectrometers equipped with microcoil-based probes. NMR probes that incorporate multiple sample chambers enable higher-throughput NMR experiments.

NMR of Flavoproteins

2003
Flavoproteins are involved in a wide variety of enzymatic reactions like oxidation, reduction and mono-oxygenation. Consequently, flavin cofactors occur in many different forms including, for example, the oxidized semiquinone and reduced states as well as the C4a-(hydro)peroxyflavin form.

ELISE NMR: Experimental liquid sealing of NMR samples

Journal of Magnetic Resonance, 2006
We present a simple, generally applicable approach to prevent sample evaporation when working at elevated temperatures in high resolution NMR. It consists of experimentally sealing the NMR sample by a second liquid (Experimental Liquid Sealing, ELISE).
