Different chromatographic techniques have been used to determine triazines. Gas chromatography coupled to mass spectrometry has been widely employed [6-11], and the use of liquid chromatography with different detectors such as ultraviolet [12-16], diode array [17,18], or mass spectrometry [19-25] has also been reported.
