A novel solid-phase microextraction device based on a through-pore sintered titanium disk (ST-SPME) was prepared and evaluated for the rapid extraction of organic pollutants from aqueous samples. The through-pores embedded in a sintered titanium disk were enlarged by HCl etching, yielding more Ti-O functional groups and a rough surface that should benefit(More)
An integrated instrumentation of a cryogenic microtrap-thermal desorption-low thermal mass (LTM) fast gas chromatographic (GC) system had been designed and evaluated for the ultrafast enrichment and separation of trace amounts of highly volatile organic compounds (VOCs) in air. The LTM fast GC column was wrapped uniformly on outer surface of a thin metal(More)
