HI everyone,
I want to know if anyone has come around a pair of noise peaks
appearing 2408 Hz from water in the gNhsqc sequence on a Varian Unity
Inova system. This problem appears to be unique to one of the two AS
600MHz spectrometers located in the room. I have done the following
without much success: changed the VT air flow, changed spectral width,
changed tof position, changed oversamp, changed RF filter on 15N
channel, changed cable from 1H channel, changed the value of 'fb'.
Any help will be much appreciated. Thanks
