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

Xiao-Wei Zhang et al.

Summary: This study assessed the matrix compatibility of several sol-gel coatings in plasma and whole blood and found that sol-gel coatings exhibited good compatibility in untreated plasma. The sol-gel hydroxy-terminated silicone oil/methacrylic acid fiber demonstrated the highest extraction ability for in vivo sampling. A direct-immersion SPME/gas chromatography-flame ionization detection method was established for the determination of phthalic acid esters in blood, which was rapid, simple, sensitive, and accurate.
