15 15 Challenges of Isolation and Elucidation Costly Sample Collection Challenging Sample Matrix Unknown and Complex Chemical Structures Quantification of Unknowns Difficult Purification-NMR Mismatches Complex NMR Spectra

16 16 Purification-NMR Mismatches Temporal –HPLC fast, NMR slow Concentration –HPLC Fractions too dilute for good NMR Solvent –Protonated –Gradients –Salts H2O ACN

17 17 The Smart Solution To Purification-NMR Mismatches Collect Fractions Put Dry Samples On One-Minute NMR Large Capacity Time-Optimized HPLC No Loop Monster No SPE Concentrator Concentrated Sample No Protonated Solvent Some salt OK Highest Mass S/N Automatic Dissolution No Solvent Supression No Shimming Evaporate HPLC Solvent

18 18 Analytical Scale Purifications Right-sized for CapNMR Scrape off a spot into filter. Add DMSO-d6, spin. Collect fractions at analytical scale HPLC Automatic Dissolution with DMSO-d6 A
