Have you ever wished that the NMR spectrometer could calculate the right number of transients that would ensure an acceptable signal-to-noise result for any experiment, and all you needed to supply was the concentration of your sample? Think how time-efficient that would be. Avoid having to re-acquire the data if you guessed low or wasting valuable magnet time if you guessed high. Adaptive NMR is a new tool in VnmrJ 3.1 that maximizes the time-efficiency of your experiments. By looking up a signal-to-noise threshold for an experiment in a user-configurable list, the software will intelligently and automatically set the number of transients necessary to achieve that threshold, or better.
A one-time calibration of a Proton spectrum of known concentration, stored in the probe file, is all that is needed to enable Adaptive NMR. There are no limitations on the observe nucleus, pulse sequence complexity, or the dimensionality of the experiment. It is possible to adjust the acceptable threshold for any individual experiment, and the calculation will adapt to suit next time around. Adding a new experiment to the list or changing a threshold is as easy as editing a text file. |
