Dear Members:
This inquirey is directed toward members with Bruker AC console systems.
Is there a standard procedure for obtaining _reproducible_ proton
integration vaules. A post-doc here has pointed out that in cases where he
is looking at small broad peaks versus relatively large, narrow peaks he can
variations of up to 200% by simply re-processing/re-integrating the file
(not re-acquiring!). In particular, I am looking for "hints" concerning:

a) Using automatic baseline correction/phase corrections;
b) Proper line-broadening values;
c) Slope/Bias corrections.

If anyone has a written procedure out there I would really appreciate
getting an Email copy.

Thanks,
