Structural elucidation and trace analysis with combined hyphenated chromatographic and mass spectrometric methods Potential of using hybrid sector mass spectrometry-time-of-flight mass spectrometry for pesticide analysis
The development of methods for analysis of triazines and their hydroxy metabolites in humic soil samples with combined chromatographic and mass spectrometric techniques is described. A two-way approach was used for separating interfering humic substances and for performing structural elucidation of the herbicide traces. Humic soil samples were extracted by supercritical fluid extraction and analysed both by HPLC-particle beam MS and a new MS-MS method. The new MS-MS unit is of the tandem-sector field-time-of-flight-MS type.
