CPE-Sylgard-GLDA is chosen because it gives us a high peak and good peak area compared with CPE-Sylgard and CPE-Sylgard-BMIMBr. The recovery extractions of CPE-Sylgard-GLDA are obtained in the range of 80–99% as the percentage of relative standard deviation (,RSD,) is less than 10. The LOD and LOQ are 0.05 ppm and 0.18 ppm, respectively.
