Dear LCQ users
In nanospray (Protana) of C8-cleaned-up in-gel digests, spraying at
0.7kV in 0.2%formic/70% MeOH I frequently see random spikes in
profile mode (largely filtered out in centroid). By collecting a
number of scans and averaging, the spikes don't really affect the
data quality but I wonder if anyone else has seen this and knows the
cause of such annoying features.
