LC-MSMS以及TraceFinder软件分析三嗪类除草剂

　　Abstract：

　　Thermo Scientific TraceFinder Sofeware includes built-inworkflow for streamlining routine analyses in environmental and food safety laboratories.By incorporating a databases of liquid chromatography-mass spectrometry(LC/MS) methods that can be customized to include unique compounds, TraceFinder allows the analyst to access commonly encountered contaminants found in the enviroment. To demonstrate the capabilities of this software,a mixture of triazine compounds spiked injections of 20 mL samples(with on-line precincentration),low-and sub-pg/mL(ppt) levels were detected The ability to analyze these drinking water samples with on-line preconcentration saves cinsiderable time and expense compared to solid phase extraction techniques.

　　Conclusion：

　　In the application note, TraceFinder Sofeware was used in conjunction with an online preconcentration system,EQuanTM,for the robust and reroducible analysis of large vilumes of drinking water.Triazines were quantitated at the sub-ppt level,and several commercial bottled drinking water sample and one sugar-free sada sample were analyzed for the presence of triazines.
