Continuous on-line monitoring of biomolecules based on automated homogeneous enzyme-linked competitive binding assays

State of the art in on‐line techniques coupled to flow injection analysis FIA/on‐line‐ a critical review

“…Koizumi and Suzuki 108] proposed an FIA method for the determination of total aliphatic amines in foods and alcoholic beverages, which employs a combination of an on-line liquid-liquid extraction and a PTFE membrane phase separator. A method for the determination ofpolyphenols in olive-oils using a flow injection/liquid-liquid extraction system has been proposed by Luque de Castro et al 166 109]. Phenol in waste water streams at low and sub ppm levels was determined by Melcher et al 110] using a flow injection system with on-line extraction of the analyte and on-line liquid chromatographic detection.…”

“…The use of automatic on-line systems for monitoring fermentation processes has been widely cited in the literature [11,[161][162][163][164][165]; however, these authors have not mentioned FIA by name, but they talk about autoanalysers, especially those based on air-segmented flow [166] and which are commercially available [167,168].…”

Micro-flow-injection analysis (μFIA) immunoassay of herbicide residue 2,6-dichlorobenzamide – towards automated at-line monitoring using modular microfluidics

“…However, the concept of automated immunosensing has emerged as a part of system development for long-term monitoring of analytes. Along with expensive and complex centrifugal analysers and air-segmented continuous flow system, 11 flow-injection immunoanalysis (FIIA) systems have pioneered the development. The FIIA concept is a combination of batch-based immunoassay and flow-injection analysis (FIA) methodology originally described by Ruzicka and Hansen in 1975.…”

Flow‐injection analysis for on‐linemonitoring of nutrients (ammonia and nitrite) in aquaculture

“…Flow injection analysis (FIA) is an automatic technique which is highly suitable for on-line monitoring [1][2][3][4][5][6]]. The aim of this research was to show the potential of FIA in aquaculture by developing the conventional batch methods usually used for monitoring in fish hatcheries in an automated unsegmented-flow fashion.…”
