A porous layer open tubular monolith on microstructured optical fibre for microextraction and online GC-MS applications

Abstract

A microextraction device comprising a porous layer open tubular (PLOT) polymer housed in a microstructured optical fiber has been shown to be an attractive tool for analyte extraction and coupling to GC-MS as a cost-effective alternative to traditional SPME. This paper details the fabrication of a poly(styrene-co-divinylbenzene) PLOT optical fibre microextraction device and its use in the extraction of polyaromatic hydrocarbons (PAHs) in aqueous solution. Good linear calibrations were obtained with R2 values above 0.970 for five PAHs analyzed, with percent relative standard deviation values of 22.2 to 43.6% for PAH standards with concentrations ranging from 0.1 to 100 ppm. In addition, the robust poly(styrene-co-DVB) PLOT optical fibre porous polymer microextraction (PPME) device appears to retain its effectiveness with repeated use over an extended period of time.
