✦ Synopsis
A novel titaniumÈsapphire high-pressure NMR cell equipped with a pressure sensor is presented. It enables the accurate and continuous in situ determination of the pressure in samples under pressure of gases and in supercritical
The homogeneity over the cell in commercial probes is excellent. The usefulness of this NMR CO 2 . cell is demonstrated in several 17O and 14N experiments in supercritical Furthermore, 1H NMR with con-CO 2 . comitant monitoring of the hydrogen gas consumption during a hydrogenation reaction in solution is treated. Important characteristics are the accuracy combined with simplicity and Ñexibility of operation.
