Matrix compatibility of typical sol–gel solid-phase microextraction coatings in undiluted plasma and whole blood for the analysis of phthalic acid esters

Abstract: Sol-gel materials have been widely used for solid-phase microextraction (SPME) coatings due to their outstanding performance; in contrast, sol-gel SPME coatings have seldom been used for in vivo sampling. The main reason is that their matrix compatibility is unclear. In order to promote the application of this type of coating and accelerate the development of in vivo SPME, in this study, the matrix compatibility of several typical sol-gel coatings was assessed in plasma and whole blood using phthalic acid este… Show more

“…Increasing from DMP to DBP, the enrichment of the target compounds by the CMPs coating increases with log Kow. The results show that the PAE extraction capacities of the CMP-coated bers are proportional to the hydrophobicity of the analyte, and there is a hydrophobic interaction between the coating and analyte (Zhang et al 2022).Comparing the extraction performance of the CMP-coated DIDP and CMP-coated DPHP, the enrichment of DIDP with high log Kow was higher than that of DPHP with low log Kow. This may be due to the presence of a "hydrophobic-hydrophobic" force.…”

“…Effective sample pretreatment is an important means to avoid food matrix interference and improve detection sensitivity. 13,14 In recent years, commonly used pretreatment methods mainly include liquid–liquid extraction (LLE), 15 solid-phase extraction (SPE), 16 solid-phase microextraction (SPME), 17 magnetic solid-phase extraction (MSPE), 18 etc. LLE has a wide range of applications, but it requires large amounts of organic solvents and is a labor-intensive process.…”
