Ordered mesoporous carbon/Nafion as a versatile and selective solid-phase microextraction coating

Ordered mesoporous carbon film as an effective solid-phase microextraction coating for determination of benzene series from aqueous media

“…The extraction efficiencies revealed by the peak areas of the OMC fiber towards the benzene series are 2.0e5.5 times higher than those of the commercial PDMS (100 mm) fiber. The improved extraction efficiency is ascribed mainly to the large specific surface area, the relatively hydrophobic surface and the pep stacking interaction between OMC and benzene rings in benzene series [42].…”

“…After that, CMK-3 [15] and CMK-5 [26] were also applied as SPME coating by the similar preparation procedure for analysis of the phenolic compounds in the water sample. More recently, Zeng et al [27] immobilized another kind of OMC materials onto a stainless steel wire using Nafion as binder to prepare an OMC/Nafion SPME fiber. Although the above mentioned OMC fibers indicated enhanced SPME performance, the preparation process of such coatings was a tedious and two-step process including pre-synthesis and immobilization of OMC powder.…”

Determination of amphetamines in biological samples using electro enhanced solid-phase microextraction-gas chromatography

“…4.2 nm. The N 2 adsorption-desorption isotherm indicated the OMC possessed large specific surface area of 1019 m 2 g -1 and maximum pore volume of 1.46 cm 3 g -1 [43]. The OMC/Nafion coated fiber was also characterized using scanning electron microscopy (SEM).…”

“…The OMC/Nafion coated fibers were prepared as reported earlier with slight modification [43]. OMC and Nafion were separately placed into Teflon tubes to make their depth in the tubes 1 cm.…”

Highly sensitive copper fiber-in-tube solid-phase microextraction for online selective analysis of polycyclic aromatic hydrocarbons coupled with high performance liquid chromatography

“…Nowadays, various forms of SPME device have been developed such as fibers [4,5], tubes, stirrers, membranes, etc. [6][7][8][9].…”
