Roger Kautz, Northeastern University, Boston, MA Title: Toward An Optimized LC-MS-NMR Strategy: Using a CapNMR Probe With Fully Automated Sample Loading using a Novel Segmented Flow Analysis Loading Technique Some practical techniques for loading and processing routine samples will first be discussed. For LC-MS-NMR analysis, we have integrated two novel LC-MS and NMR technologies to capitalize on the highest sensitivity available for each technique and accommodate the disparities between MS and NMR in their sample mass and time requirements. For LC-MS, conventional 4 mm columns allow validated LC methods and equipment to be used; a NanoSplitter interface provides the phenomenal LC-MS sensitivity of nanoelectrospray, while collecting 100-fold more material for NMR than capillary separations. In an offline NMR strategy the fractions, concentrated by drying in 96-well plates, can be stored until LC-MS data is evaluated and the NMR is available. Comprehensive LC-NMR data of all fractions may be acquired in unattended automation over a night or weekend, with LOD's under 200 ng. In supervised automation or manual loading of single samples, HSQC can be obtained from 20 µg, interpretable 1D spectra from 50 ng, overnight. A "segmented flow" method of handling miniscule samples in microfluidic systems as discrete "plugs", like droplets of water in oil, can load 1 µL samples with negligible (<5%) losses or dilution, increasing sample efficiency several-fold.
