Triazole-derivative metabolites can occur in plant and animal materials and in water. Due to their physical-chemical properties, their analysis in complex matrixes is very difficult. The objective of this work was to develop a method for the analysis of these analytes that is easy to handle, quick, and enables quantification at a residue level of 0.01 mg/kg. Using the LC-differential mobility spectrometry/MS/MS system, cleanup and derivatization processes became unnecessary. For more than 10 representative plant materials it could be shown that the new method is valid and reproducible, thus leading to accurate and reliable results.
三唑衍生物代谢物可存在于动植物材料及水中。由于其物理化学性质，在复杂基质中对其进行分析非常困难。本研究的目的是开发一种易于操作、快速且能够在0.01 mg/kg残留水平进行定量分析的这些分析物的方法。使用液相色谱-差分离子淌度谱/串联质谱系统，无需净化和衍生化过程。对于10多种代表性植物材料，可以证明新方法是有效的且可重现的，从而得出准确可靠的结果。
