Reduction of motion artifacts in NMR

NMR spin echo signals, acquired on a MWD logging tool, are susceptible to errors magnetic flux density has a gradient and the magnet on the logging tool is moving relative to the earth. The errors can be corrected by having the excitation pulse cover a smaller or a larger volume than the refocusing pulses. Correction may also be made by selective saturation, or by echo averaging.

Methods for making microarrays and their uses

The present invention provides microarrays that can be analysed by more than one technique using a non-covalent ligand attachment strategy to solid supports such as indium tin oxide (ITO) covered transparent glass slides. This provides, inter alia, glycan arrays on a micrometer scale which allow multimodal readout by MALDI-Tof-MS, fluorescence and optical microscopy. Glycans functionalized with a C5-aminolinker were attached in situ on a picomolar scale to a hydrophobic tag bound to this surface, thus avoiding the wasteful off-chip ligand tagging of other approaches. Glycan arrays prepared using this methodology were analysed both with a fluorescence scanner and by on-chip MALDI-mass spectrometry in a series of glycomics experiments specifically requiring a multimodal readout.
