Voltammetric sensors with laterally placed working electrode are an interesting alternative to classic electrodes since they offer enhanced performance in electroanalysis. Their characteristics include easier preparation for measurement, removal of interferences and gas bubbles, amplification of mass-transport, and possibility of miniaturization and automation. In this review, construction and characteristics of the custom-designed in our team cyclically renewable, silver, gold, bismuth, glassy carbon, ceramic and amalgam annular band, bi-band, ring, and multidisc electrodes are discussed in detail. They represent the current trends in electroanalysis, aimed at reducing of amount of the used toxic electrode materials, like mercury and its compounds, and organic solvents used for a sample preparation, and are coherent with the concept of Green Chemistry. For each sensor type available strategies for mechanical and electrochemical surface renovation/activation before measurement are elucidated and evaluated on the basis of interpretation of voltammetric and tensammetric curves. Particular attention is put on electrochemical characteristics of the described sensors and their application for determination of trace amounts of metal ions and their complexes, organic compounds, and surface-active substances by means of tensammetry, and anodic, cathodic, adsorptive and catalytic adsorptive stripping voltammetry. Final considerations are addressed to the possibility of measurement automation and related future prospects.

“…A study demonstrated that voltammetric signals obtained using metallic electrodes in a simple supporting electrolyte constitute an adequate tool for distinguishing wines and Scotch whiskies (Wójcik et al., 2019). The study demonstrated that profiling was possible if the faradaic component of the differential pulse voltammetry (DPV) signal was used while disregarding the capacitive charging current.…”

“…A chemometric algorithm that works in three‐dimensional space (alternating trilinear decomposition), as well as the DPV technique, was used for the decomposition of the total current recorded. In addition, in comparison with the platinum disk electrode, the construction and operation of the quadruple‐disk iridium electrode (an environmentally friendly voltammetric sensor) was presented (Wójcik et al., 2019). It was observed that when the disturbing and non‐informative capacitive current were rejected, an optimal effect in profiling was achieved.…”

In order to safeguard authentic whiskey products from fraudulent or counterfeit practices, high throughput solutions that provide robust, rapid, and reliable solutions are required. The implementation of some analytical strategies is quite challenging or costly in routine analysis. Qualitative screening of whiskey products has been explored, but due to the nonspecificity of the chemical compounds, a more quantitative confirmatory technique is required to validate the result of the whiskey analysis. Hence, combining analytical and chemometric methods has been fundamental in whiskey sample differentiation and classification. A comprehensive update on the most relevant and current analytical techniques, including spectroscopic, chromatographic, and novel technologies employed within the last 5 years in whiskey analysis for authentication, discrimination, and quality control, are presented. Furthermore, the technical challenges in employing these analytical techniques, future trends, and perspectives are emphasized.

“…Based on the differential pulse voltammetry technique's selected current component, Wójcik et al [136] employed voltametric sensors to profile wine and Scotch whisky samples with a complicated composition using voltametric sensors. This novel technique has the potential to represent a significant step forward in the development of voltametric complicated sample profiling, as well as the fabrication of electronic tongues.…”

There is and will always be the need to provide authentic and safe alcoholic beverages. To achieve this goal, researchers are constantly looking for innovative and practical approaches to analyze their samples and control their quality. Quality control can be challenging in the spirits industry due to their production (mashing, fermenting, distilling, aging, packaging) and their complex chemical composition. To assess the quality and safety of alcoholic beverages, a variety of analytical procedures have been developed and are currently in use. Although these laboratory-based approaches offer a high level of sensitivity, they can be both time-consuming and costly. Therefore, it is an ongoing need to advance simpler, faster, more precise, field-deployable, and more sensitive instruments to identify chemicals and abnormalities in alcoholic beverages. We believe many needs can be addressed using microfluidic technologies, sometimes referred to as lab-on-a-chip devices. In this review, we will discuss recent significant advancements in microfluidics for the assessment of alcoholic beverage products. The analysis and viewpoints presented in this study are intended to stimulate continued development of microfluidic devices in the spirits sector and other food safety testing and monitoring fields, benefiting human health and overall well-being.
