| Abstract: | Summary Public health pesticides in two-component mixed solutions were analyzed using solid-phase microextraction (SPME) coupled with
gas chromatography (GC) and gas chromatography—mass spectrometry (GC-MS). The two-component mixed solutions used were allethrin
mixed with cyfluthrin, cypermethrin mixed with tetramethrin, and transfluthrin mixed with cyfluthrin. Quantitative SPME-GC
and SPME-GC-MS analyses using calibration and standard addition methods were evaluated. Using SPME pretreatment saved several
tens to hundreds of mL of organic solvent. Quantitative analyses of the SPME-GC and SPME-GC-MS using the calibration and standard
addition methods showed promise for simple, fast, and solventless public health pesticide analysis. |
