Application of poly(butyl methacrylate-co-ethylene glycol dimethacrylate) monolith microextraction coupled with high performance liquid chromatography to the determination of polycyclic aromatic hydrocarbons in smoked meat products

This paper presents a study of the synthesis of a polymer monolith column and its application to the analysis of PAHs in smoked meat products. A poly(butyl methacrylate-co-ethylene glycol dimethacrylate) monolith capillary has been successfully prepared with in situ polymerization method. The polymer monolith microextraction combined with HPLC determinations is employed for the analysis of naphthalene , biphenyl , phenanthrene , and anthracene . Various parameters affecting the extraction efficiency have been investigated and optimized. Under the optimum experimental conditions, the method provides an acceptable linearity (2–10,000   μg/L), low limits of detection (1.4–2.0   μg/L), and good precision (intraday relative standard deviations   <   4.1%, interday relative standard deviations   <   5.7%). When applied to the determination of the four PAHs in smoked meat samples, recoveries are obtained in the range of 86.6–101.5%.
