We describe a pretreatment method before determining the total fluoride in solutions containing tetrafluoroborate ion (BF4−) with ion-selective electrodes (ISEs). BF4− was quantitatively ...
A fully automated pretreatment system based on sequential injection solid-phase extraction (SPE) coupled to a graphite furnace atomic absorption spectrometer (Auto-Pret-GFAAS system) was developed to...
Third-hand smoking was quantitatively evaluated with a polymer-packed sample preparation needle and subsequent gas chromatography–mass spectroscopy analysis. The extraction needle was prepared with po...
Humic substances (HS) from well waters, fertilizers, and synthetic phenolic polymers were characterized by elemental and UV-VIS spectroscopic analyses. Capillary zone electrophoresis (CZE) with UV ab...
A capillary electrophoresis with electrochemical detection was developed for the simultaneous determination of three flavonoids (naringenin, rutin, quercetin) and ascorbic acid. It was found that nari...
Implantable fine needle-type glucose sensors with an outer diameter of less that 0.2 mm were fabricated using a low-cost and non-animal origin polyamide, γ-polyglutamic acid (PGA) as a glucose oxidas...
A series of N-substituted pyrroles having phosphorylcholine with different methylene chain lengths between pyrrole group and phosphorylcholine group were synthesized and their electropolymerizations w...
Two strategies to identify tumor cells were developed in this research via analyzing the activity of telomerase inside the cells, which is regarded as the mark enzyme of tumors. The lysate of cells wa...
A novel concept of simultaneous injection-effective mixing analysis (SIEMA) is proposed, and a SIEMA method applied to the spectrophotometric determination of palladium using a water-soluble chromogen...
In order to characterize the ion-exclusion and cation-exchange properties of an unmodified silica-gel column, the retention behaviors of Cr(VI) and Cr(III) ions were investigated using a Develosil 30-...
We propose a rapid and label-free quantitative evaluation of anti-cancer drug efficacy in apoptosis using live cancer cells cultured on a sensor chip. The resultant custom-made, high-precision surface...
The study presented in this paper concerns the extractability of rutin into an aqueous 1-butyl-3-methylimidazolium chloride (BMIM-Cl) solution. The effects of the concentrations of BMIM-Cl, amounts of...
An indium tin oxide glass electrode coated with poly(3,4-ethylenedioxythiophene), PEDOT, PEDOT-ITOE, was proposed as an electrode workable as both a reference electrode and a counter one, a reference/...
In this study, nitrobenzene in water and ice samples collected from the Songhua River after the explosion of a petrochemical plant was determined by GC/MS. The results showed that nitrobenzene was de...
