HMBC and HMQC

I seem to be having some problems with my parameter sets for our HMQC and
HMBC experiments. I am running the experiments on an AMX-600 with a X-32
and Aspect3001 computer system.

First the samples are dilute 3-4 mg(MW = 600 to 1000 gm/mole). Can I run a
HMBC and HMQC (inverse detection) on a sample this dilute. If I can, what
parameters do I need to check or calibrate before I rum the experiment. I
have checked the 90's in the decoupler and transmitter channel. Do I need
to do this for every sample or just every so often as part of my regular
calibration and shimming work.

Any help or suggestions will be gladly taken.

Thanks in advance

Chuck
