A Total Solution for the Analysis of Melamine and Cyanuric ...

most characteristic ions should be chosen to minimize signal disturbance even if their abundance is relatively lower. In this application, the influence of ion selection was demonstrated in Figure 1. With the use of more characteristic ions, the chromatogram has much less interference than the chromatogram with the highest abundance ions.
