Species formed by reaction of IL with melamine alone. Only two peaks could be interpreted. The rest are fragments either coming from impurities or fragments generated in the MALDI. It is clear that the melamine itself is not affected by the IL, although species like the 538 Da could facilitate reaction with the aldehydes.
| Peak | Chemical Species |
|---|---|
| 200 Da = [HNMP] [HSO4−], calculated 197 Da, + protonation. 536–539 Da = 539 Da calculated (516 + Na+ = 539) |
