Microcell for Nuclear Magnetic Resonance Analyses

Abstract

The use of a commercially available all-glass spherical sample-chamber microcell in combination with a time-averaging computer for nuclear magnetic resonance (NMK) analyses of microsamples has recently been reported.1 Brame2 has described a technique for trapping small gas-chromatographically isolated samples directly in such an all-glass NMR microcell. A somewhat different, easily fabricated microcell has been constructed and tested in our laboratories with excellent results. The design is a modification of a cell first described by Frei and Niklaus.3
