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.
