Air/polymer distribution coefficients for polycyclic aromatic hydrocarbons by solid-phase microextraction sampling.

Two methods to estimate distribution coefficients (K) between air and poly(dimethylsiloxane) (PDMS) coating of solid-phase microextraction (SPME) fibers for eight low molecular polycyclic aromatic hydrocarbons (PAHs) there are presented. The PDMS phases were used for determination of the coefficients according to equilibrium theory with help of a developed… CONTINUE READING
