Piperazine and N,N'-methylene bis acrylamide can be?

Hi, Friends,
These two samples are monomers to polymerize a copolymer. I am developing the method to test the residues.
Originally, I preferred to analyze them by GC. The bp of piperazine is 140'C only although two N in its structure. From the latter structure, I think it could be run in the GC. But I tried polar column and non-polar column (innowax 50-260'C and HP-1 50-320'C) seperatively, no any useful peaks can be used to quantify. So anyone have experience in analysis of these two samples, pls help me to clarify.
Thank you in advance.
