| 摘要 |
The invention concerns an NMR sample holder for NMR samples with a short sample tube of constant diameter which is clamped in a largely gas-tight fashion and with a movable plunger and a rotor. The inventive device increases flexibility compared to conventional sample holders, reduces the vapor volume over the sample liquid in the sample tube and prevents deviations from precise orientation. The invention also concerns a method for simple and safe exchange of the sample tube thereby drastically minimizing loss through breakage.
