Melamine and cyanuric acid, two compounds connected to tainted pet food, have been analyzed using matrix-assisted laser desorption ionization/time-of-flight mass spectrometry. (M+H)+ ions were observed for melamine, ammelide, and ammeline under positive ion conditions with sinapinic acid as the matrix. With alpha-cyano-4-hydroxy-cinnamic acid as the matrix, a matrix-melamine complex was observed. (M-H)- was observed for cyanuric acid with sinapinic acid as the matrix.
