I appologise very much, this is not a chromatographic message, but I guess someone out there can help me, this is my last resort:

I would like to know what the US Pharmacopeia has to say on VOLATILE ORGANIC RESIDUES IN PECTIN? How are they specified? What are the levels that are permitted?

Someone who reads this message has the book on her/his desk and can make me happy by dropping a line!

I thank you very much in advance!
