The Solid Phase Micro-Extraction (SPME) technique was applied to analyze chlorpropham in potatoes and amitraz in honey. The homogenized sample, suspended in water and stirred, was extracted with a 100 microns thick polidimetylsiloxane fiber and desorbed into the injection port of a gas chromatograph/mass-spectrometer (quadrupole) operating in single ion monitoring. Sensitivities down to 0.01 mg/Kg and linear responses in the range of 0.01-0.1 mg/Kg were obtained. The results of SPME pesticide residue analysis in potatoes corresponded to those obtained with a traditional multiresidue method.
采用固相微萃取（SPME）技术分析马铃薯中的氯苯胺灵和蜂蜜中的双甲脒。将匀浆后的样品悬浮于水中并搅拌，用100微米厚的聚二甲基硅氧烷纤维进行萃取，然后解吸到单离子监测模式下运行的气相色谱/质谱仪（四极杆）的进样口中。获得了低至0.01毫克/千克的灵敏度以及0.01 - 0.1毫克/千克范围内的线性响应。马铃薯中SPME农药残留分析结果与传统多残留方法所得结果一致。
