Determination of calcium in water by flow injection analysis — inductively coupled plasma (FIA-ICP) emission spectrometry
TL;DR: Using an 11 ml centrifugal type spray chamber, a rapid sample introduction rate of 320 injections per hour may be achieved when interfacing flow injection analysis and inductively coupled plasma emission spectrometric techniques.

Evaluation of Amperometric Dot Microsensors for the Analysis of Serotonin in Urine Samples
TL;DR: In this paper, twenty-four amperometric dot microsensors based on carbon materials, (e.g., graphite (G) and graphene (GR) and carbon nanopowder (CN)), unmodified and modified with TiO2, and phthalocyanines were evaluated and tested for their ability for the analysis of serotonin (5-HT) in biological fluids using differential pulse voltammetry (DPV).

TL;DR: In this paper, the authors present normalized proposals in the field of flow analysis for practitioners and developers in order to permit the composition of a checklist that will lead to a protocol for reporting results and systems in flow analysis.
On-line monitoring of r-captopril using an amperometric biosensor/sequential injection analysis system
TL;DR: In this article, an automated system for the on-line monitoring of R-captopril, based on the concept of sequential injection analysis with an amperometric biosensor (based on D-amino acid oxidase) as detector, is described.

Determination of isoxsuprine hydrochloride by sequential injection visible spectrophotometry
TL;DR: An automated sequential injection (SI) spectrophotometric method for the determination of isoxsuprine hydrochloride with wide linear range, low detection limit, and highly economical reagent consumption are the advantages of this automated method.
