Development of Novel Solid-Phase Microextraction Fibers
The basic principles for the preparation of SPME fibers with satisfying selectivity, sensitivity, loading capacities and stabilities are summarized here in terms of the physicochemical properties of the coating materials and the supporting substrates of SPME fibers. While the main part of this chapter focuses on the advances in developing the most widely used coating materials, including ionic ...
متن کاملPreparation and application of ionic liquid-coated fused-silica capillary fibers for solid-phase microextraction.
A simple and cost effective solid-phase microextraction device has been developed. Fused-silica capillaries were etched with ammonium hydrogen difluoride prior to coating with an ionic liquid. For comparison, both a bare fused-silica capillary and one pretreated with a Nafion membrane were coated with the ionic liquid. All three coated capillaries were employed for the head space microextractio...
متن کاملApplication of Headspace Solid-Phase Microextraction for Determination of Chloro-Organic Compounds in Sewage Samples
Solid phase microextraction (SPME) has been optimized and applied to the determination of the volatile halogenated compounds (VHCs) and semi-volatile halogenated compounds (SVHCs). Three types of SPME fiber coated with different stationary phases (PDMS-100 mum, CAR/PDMS-75 mum, PDMS/DVB-65 mum) were used to examine their extraction efficiencies for the compounds tested. Experimental parameters ...
متن کاملSynthesis and Metalation of Catechol-Functionalized Porous Organic Polymers
Robust catechol-functionalized porous organic polymers (POPs) with tunable porosities (560−1050 m/g) and degrees of functionalization were synthesized using a cobaltcatalyzed acetylene trimerization (CCAT) strategy. Post-synthesis metalation can be readily carried out with a wide range of metal precursors (Cu, Mg, and Mn salts and complexes), resulting in metalated POPs with enhanced heat of hy...
متن کاملEvaluation of Carbon Nanotubes Functionalized Polydimethylsiloxane Based Coatings for In-Tube Solid Phase Microextraction Coupled to Capillary Liquid Chromatography
In the present work, the performance of carbon nanotubes (c-CNTs) functionalized polydimethylsiloxane (PDMS) based coatings as extractive phases for in-tube solid phase microextraction (IT-SPME) coupled to Capillary LC (CapLC) has been evaluated. Carboxylic-single walled carbon nanotubes (c-SWNTs) and carboxylic-multi walled carbon nanotubes (c-MWNTs) have been immobilized on the activated surf...
