Dear All

I found there are artifacts from 0-2 ppm when I used water-gated HSQC (hsqcfpf3gpphwg) for water suppression, but there is no artifact when I used (hsqcetfpf3gpsi) coherence selection for water suppression on 800 MHz cryoprobe. See pictures. I ran both experiments on 600 RT probe without any artifacts. Any suggestions are appreciated.

Thanks,
