From flow injection to bead injection.
In this Report, we introduce a new methodology applicable to the entire range of traditional reagent and solid-phase assays. Known as bead injection (BI), this technique influences diverse fields of research, including chemical sensors, microfabrication, bioassays, affinity chromatography, spectrophotometry, and electrochemistry. This is because BI combines the advantages of solid-phase chemist...
متن کاملSimple flow-injection system for the simultaneous determination of nitrite and nitrate in water samples.
A novel spectrophotometric reaction system was developed for the determination of nitrite as well as nitrate in water samples, and was applied to a flow-injection analysis (FIA). The spectrophotometric flow-injection system coupled with a copperised cadmium reductor column was proposed. The detection was based on the nitrosation reaction between nitrite ion and phloroglucinol (1,3,5-trihydroxyb...
متن کاملSimple sequential injection analysis system for rapid determination of microalbuminuria.
A simple, specific and sensitive sequential injection analysis (SIA) system based on non-immunoassay fluorescent detection has been developed for the determination of urinary albumin. The specific binding of the dye Albumin Blue 580 (AB 580) to albumin in urine generated high emission fluorescent signals. The excitation and emission wavelengths were set at 590 and 610 nm, respectively. The anal...
متن کاملDetermination of chloride in admixtures and aggregates for cement by a simple flow injection potentiometric system.
A simple flow injection system using three 3-way solenoid valves as an electric control injection valve and with a simple home-made chloride ion selective electrode based on Ag/AgCl wire as a sensor for determination of water soluble chloride in admixtures and aggregates for cement has been developed. A liquid sample or an extract was injected into a water carrier stream which was then merged w...
متن کاملBead-injection determination of total mercury in river water samples.
A bead-injection system is proposed for total mercury determination in river-water samples. The procedure is based on the introduction of a defined quantity of a resin suspension in the flow system. The selected beads are packed inside of a flow cell and the formed resin mini-column constitutes the optical path. The sample volume is then selected, and its passage by the mini-column allows reten...
