N-M-R as revealing as your fingerprint Because it offers a completely fresh approach to the study of chemical systems, Va rian s Model V-4300 High Resolution n-m-r (nuclear magnetic resonance) Spectrometer has become an instru ment of major importance to analytical chemists everywhere. Now at work in research laboratories throughout America, this remark able new device detects signals from H1, F'f P3! B", C 1 3 H * N'? and several other nuclei, revealing the character of the chemi cal environment. LABCONCO

apparatus
High Resolution n-m-r techniques permit rapid, non-destructive analysis of small liquid samples, including melted solids, solids in solution and liquefied gases. Prominent applications include iden tification of functional groups, equilibrium and kinetic studies, assignment of structural formulas and analysis of multi-component mixtures.
