Journal ArticleDOI
Disposable ionic liquid coating for headspace solid-phase microextraction of benzene, toluene, ethylbenzene. and xylenes in paints followed by gas chromatography-flame ionization detection
TL;DR: Compared to the widely used commercially available SPME fibers, this proposed disposable IL-coated fiber has much lower cost per determination, comparable reproducibility (RSD < 11%), and no carryover between each determination.
Journal ArticleDOI
Determination of sulfonylurea herbicides by continuous-flow liquid membrane extraction on-line coupled with high-performance liquid chromatography.
TL;DR: This proposed method was applied to determine MSM and DPx-A 7881 in seawater, tap water, and bottled mineral water with spiked recoveries in the range of 83-95% for MSM and 88-100% for DPX-A7881, respectively.
Journal ArticleDOI
Selenium speciation by high-performance anion-exchange chromatography-post-column UV irradiation coupled with atomic fluorescence spectrometry.
TL;DR: High-performance anion-exchange chromatography coupled with atomic fluorescence spectrometry (HPAEC-AFS) established a technique for the speciation of selenomethylcysteine, selenocystine and selenite and good spiked recoveries from 86 to 103% were obtained.
Journal ArticleDOI
Automatic trace-enrichment of bisphenol A by a novel continuous flow liquid membrane extraction technique
TL;DR: In this paper, a continuous flow liquid membrane extraction technique was used to enrich 50 mug L-1 BPA using dichloromethane as liquid membrane, achieving over 200-fold enrichment of BPA after a 40 min enrichment time.
Journal ArticleDOI
Direct amino acid analysis method for speciation of selenoamino acids using high-performance anion-exchange chromatography coupled with integrated pulsed amperometric detection.
TL;DR: Three selenoamino acids could be baseline-separated from 19 amino acids using gradient elution conditions for amino acids and determined under new six-potential waveform using HPAEC coupled with integrated pulsed amperometric detection (IPAD).
