Notes:
Watergate is the first supression method which could compete against presaturation. It is relatively straightforward to be used, and can easily be appended to any NMR-experiment/pulse sequence. However, watergate still requires a good deal of setup/pulse optimization. Reward is the significantly better water supression than with presat. In principle, it has the same restriction as presat, i.e. it fully saturates or better excites the water it filters out!
