A Nalorac 4-Nucleus probe has been installed on VXR400 for routine operation, replacing the Broadband probe. Like I400, users can now acquire 1H, 13C, 19F, and 31P spectra on the VXR400 without need of probe switch/tuning.
Please note that the old parameters you saved previously with the Broadband probe should NOT be used for the newly installed 4-Neclues probe (i.e. do not open one of your old FID files and click “acquire” or type “ga” to acquire new data). You should go through the standard experiment set-up procedures: click on “Experiments” in the menu bar then select a nucleus or an experiment. This would ensure to load appropriate parameters that were calibrated for the currently installed probe.
