AV500 – GRADIENT ASSISTED SHIMMING – Topshim program

Many of you might be aware that the AV500 console acquired the ability to do fully Automatic shimming using the Topshim program from within Topspin.  The system uses either 1H or 2H NMR resonance signals to accomplish this along with gradient coils placed in the NMR probe.  This means that no matter which lock solvent you use, whether it is a deutero- or proteo- solvent,  it can do this automatic shimming.  This is not only a convenience but saves time also substantially.  We encourage you to explore this capability of the spectrometer to your advantage, even during your routine NMR.  Please ask one of us if you need further assistance.
