“…Micro-ow-injection analysis (mFIA) 1,2 incorporates the ow injection analysis (FIA) method on a microuidic device and is capable of high-throughput analysis because of the on-chip integration of analytical operations such as mixing, 3,4 reaction, [5][6][7] separation, 8,9 and detection. [10][11][12][13] On-chip integration is superior to conventional FIA methods as it reduces analysis time, as well as sample and reagent consumption.…”

Determining the distributions and variations of chemical elements in oceans has significant meanings for understanding the biogeochemical cycles, evaluating seawater pollution, and forecasting the occurrence of marine disasters. The primary chemical parameters of ocean monitoring include nutrients, pH, dissolved oxygen (DO), and heavy metals. At present, ocean monitoring mainly relies on laboratory analysis, which is hindered in applications due to its large size, high power consumption, and low representative and time-sensitive detection results. By integrating photonics and microfluidics into one chip, optofluidics brings new opportunities to develop portable microsystems for ocean monitoring. Optofluidic platforms have advantages in respect of size, cost, timeliness, and parallel processing of samples compared with traditional instruments. This review describes the applications of optofluidic platforms on autonomous and in situ ocean environmental monitoring, with an emphasis on their principles, sensing properties, advantages, and disadvantages. Predictably, autonomous and in situ systems based on optofluidic platforms will have important applications in ocean environmental monitoring.

“…14 In the flow method development, zone penetration is usually employed in the initial screening phase, and the changes in the overlapping area are judged by appearance. [15][16][17] Even if the numerical values were given, it was not exposed which approach was employed for zone penetration evaluation. Most common approach used in development of sequential injection and flow analysis methods is still univariate optimization.…”

In the flow method development, zone penetration studies are usually conducted as a part of initial screening phase. A lack of an appropriate tool can keep these studies on the level of rough estimations. The developed LabVIEW virtual instrument (VI) which processes peak signals and calculates the overlapping area and fundamental peak-related parameters was used for calculations in experiments that are modelling sample and reagent plug interaction within liquid conduits. The reliability of the predictions was initially confirmed on the artificial data set based on thirty-six files covering all the different types of cases that can be foreseen. In the continuation, volumes of model solutions, propelling flow rate, and coil length in the sequential injection analysis system, were varied by following Box-Behnken response surface design. In three examples, it is demonstrated how the VI can help us plan further experiments in the range which ensures efficient zone overlapping, economic exploitation of reagent plug and adequate dispersion. The application of the VI is not limited just to flow-based chemistry, it can also be useful in spectroscopy and chromatography. To utilize the graphical user interface, it is not necessary to have the LabVIEW program installed.
