Novel use of a dual-zone restricted access sorbent: normal-phase solid-phase extraction separation of methyl oleate from polynuclear aromatic hydrocarbons stemming from semi-permeable membrane devices
Ke. Gustavson et al., Novel use of a dual-zone restricted access sorbent: normal-phase solid-phase extraction separation of methyl oleate from polynuclear aromatic hydrocarbons stemming from semi-permeable membrane devices, J CHROMAT A, 883(1-2), 2000, pp. 143-149
A normal-phase solid-phase extraction (SPE) method was developed utilizing
a dual-zone restricted-access sorbent to separate methyl oleate from the 16
US Environmental Protection Agency priority-pollutant polynuclear aromatic
hydrocarbons in a hexane matrix. This technique represents a new developme
nt in SPE methodology expanding the limited number of available normal-phas
e SPE sorbents. While based on a specific application (removal of methyl ol
eate from semipermeable membrane device extracts), this cleanup method coul
d easily be adapted for other uses requiring the removal/isolation of methy
l oleate and potentially related compounds. (C) 2000 Elsevier Science B.V.
