Dear mominbilal,

Check the compendium methods. GC headspace methods works for DMI, a cyclic urea.

Sincerely,

Given that a google search for analytical methods for each of these turns up many methods, I assume you have done such a search and have a qustion in the selection of one? A more specific question woule be helpful for providing you with a more specific answer.

Check out some of the HILIC literature, it is perfect for the analytes you mentioned and very easy to do.
