Pesticide residue analysis in medicinal herbs is a challenging task because of the matrix effect and its influence on quantitative despite continuous development several new analytical methods instrumentations. In this study, modified QuEChERS method was developed for indoxacarb by using conventional instrument, gas chromatography micro-electron-capture-detector (GC–μECD), comparing it with chr...

For the quantitative analysis of phthalates in polymers, a thermal desorption (TD)-GC-MS method was compared with solvent extraction (SE)-GC-MS methods which require the long pretreatment procedures using large amount of harmful organic solvents. Calibration curves of TD-GC-MS showed good linearity (r(2)>0.9997) and low method detection limit (<30mg/kg with 9.0% RSD). Quantification results for...
