Hello Dear Colleagues,

I need your help about 70 % DMA HCl analysis. I want to determinate the monomethylamine, trimethylamine and ammonia in % 70 DMA HCl.

Previously, I tried IC-Conductivity and HS-GC/MS method. But, I did not get good resolution between DMA, MMA and TMA.

Could you give me an advise analysis method or technic?

Thanks in advance
