I have obtained food samples from the local zoo as well as hair
samples to compare their carbon signatures.  The samples include
raw carrots, apples, celery, hay, pellet food, herring, omnivore biscuits,
sweet potato, knuckle bone, and a kind of kibble for the large cats...   I
need to know what the procedure is to process and prepare these
samples for mass spec analysis...  It would also be helpful to know
how much sample I need for analysis.

Thanks-
