Abstract
A method and apparatus for structural elucidation and determination of a nanoliter size sample of analyte. The method includes separating the analyte using a microseparation technique and then substantially simultaneously analyzing or detecting the sample using a nuclear magnetic resonance (NMR) spectrometer. The apparatus includes an RF microcoil positioned for operable communication with a capillary member of the microseparation system and the NMR spectrometer to provide enhanced sensitivity and improved signal-to-noise ratio of the NMR spectrometer necessary to accurately analyze or detect nanoliter size samples.
