An overview of sequential injection chromatography
Analytica Chimica Acta, 2007New generation of sequential injection analysis (SIA) called sequential injection chromatography (SIC) has already been consolidated as a good alternative of high performance liquid chromatography (HPLC) for fast analysis of simple samples. Benefits of flow methods are automation, miniaturization and low sample and mobile phase consumption ...

Sequential injection immunoassay utilizing immunomagnetic beads
Analytical Chemistry, 1992A novel sequential injection immunoassay (SIIA) method is described which utilizes immunomagnetic beads to investigate short-time antibody binding. The method is versatile and flexible and may therefore be adapted to many different applications. Initial results for a competitive assay are also presented.

Two-dimensional separation by sequential injection chromatography
Journal of Chromatography A, 2020Sequential injection chromatography (SIC) is an alternative for fast chromatographic separations with low consumption of organic solvents. However, its separation capacity is restricted by the use of short chromatographic columns and the limitations for gradient elution.

Multicomponent techniques in sequential injection
The Analyst, 1995The application of multicomponent techniques in sequential injection analysis is considered. Such a scarcely selective chromogenic reagent as 4-(2-pyridylazo)resorcinol allowed the simultaneous spectrophotometric determination of Ca and Mg in environmental samples.

Fundamentals of sinusoidal flow sequential injection spectrophotometry
Analytical Chemistry, 1991A rational design of the sequential injection analyzer is based on description of the mutual penetration of sample and reagent zones, which are sequentially stacked into a tubular conduit and then injected into a reactor and transported toward the detector by means of a carrier stream, flowing at a preprogrammed rate.

Sequential injection spectrophotometric determination of etilefrine hydrochloride
Il Farmaco, 2004A simple, fast, economical and automated sequential injection spectrophotometric method for the determination of etilefrine hydrochloride is developed. The method is based on the condensation reaction of etilefrine hydrochloride with 4-aminoantipyrine in the presence of alkaline potassium hexacyanoferrate and the absorbance of the colored product ...

New horizons in sequential injection kinetic analysis
Analytical and Bioanalytical Chemistry, 2002The need to measure several quantities rapidly in the same sample has prompted the development of automated methods of analysis that in both the continuous and discontinuous modes offer the possibility of simultaneous determinations. The application of pH gradients and differential kinetic determinations dominate the simultaneous determination of two ...

Quaestiones Mathematicae, 2015
Injectivity with respect to pure monomorphisms was studied before incategories of modules and categories of acts. In this paper we study this notion with respect to sequentially pure monomorphisms.Although the Baer criterion for injectivity (weakly injectivity implies injectivity) is true for modules over a ring (with an identity), it is an open ...

Sequential-injection extraction for sample preparation
Analytica Chimica Acta, 1997Abstract This report introduces a flow-based extraction method where an aqueous sample and organic solvent are injected sequentially into an extraction coil, then mixed and separated due to the differential flow velocities of the aqueous and organic phases.

A sequential injection microfluidic mixing strategy
Microfluidics and Nanofluidics, 2005A novel micromixing strategy is presented, which exploits the axial diffusion of a continuous sequence of discrete samples in a microchannel expansion. Mixing of a continuous sequence in an electroosmotic flow through a sudden expansion region is first modeled assuming an ideal, square-wave injection.
