Nanostructured titania-based solid-phase microextraction (SPME) fibers were fabricated through the in situ oxidation of titanium wires with H 2 O 2 (30%, w/w) at 80°C for 24h. The obtained SPME fibers possess a ∼1.2μm thick nanostructured coating consisting of ∼100nm titania walls and 100–200nm pores. The use of these fibers for headspace SPME coupled with gas chromatography with electron...
A miniaturized capillary electrophoresis (CE) system with UV-Vis detection was coupled to a flow injection (FI) system for achieving high throughput continuous sample introduction. The cassette of a commercial CE instrument was modified to hold a 6.5cm long silica capillary and a flow-through waste reservoir. The cassette was inserted into the flow-cell chamber of a commercial UV detector, with the...
