Modern Analytical Techniques Applied for Qualitative and Quantitative Analysis of Ingredients and Inspect of Composition of Dietary Supplements

Dear Colleagues,

A food supplement is a foodstuff whose purpose is to supplement a normal diet and is a concentrated source of vitamins, minerals or other substances with nutritional or other physiological effects, single or complex, placed on the market in a dosage form.
The dietary supplement may be introduced in the form of capsules, tablets, dragees and other similar forms, powder pods, liquid ampoules, dropper bottles and other similar forms of liquids and powders intended for consumption in small, measured unit quantities.
The maximum level of vitamins and minerals and other substances with a nutritional or other physiological effect ensures that the typical use of the dietary supplement in accordance with the information provided in the label will be safe for human health and life.
On the other hand, contaminations of dietary supplements, e.g., by pesticides or heavy metals, may pose a threat to a wide range of consumers. Therefore, it is extremely important to precisely control the composition of dietary supplements: The quality and quantity of ingredients, and whether their composition complies with the manufacturer's declarations.
Many modern analytical techniques are used to precisely inspect the composition of dietary supplements. The method selected depends on the complexity of the sample, the nature of the matrices and the analytes, and the analytical techniques available. The most efficient approach to analyte identification and quantitative analysis involves the use of chromatographic methods.
The following chromatographic methods are most frequently applied to determination of components of dietary supplements: High-performance liquid chromatography (HPLC), ultrahigh-performance liquid chromatography (UPLC), and gas chromatography (GC). These methods are used for quantitative analysis of complex mixtures of compounds in different forms of dietary supplements.
This Special Issue is planned as a topic that presents, in a properly structured manner, up-to-date, state-of-the-art information on the very important field of modern analytical techniques, including high-performance chromatographic techniques coupled with appropriate/sensitive detection techniques (e.g., DAD, FLD, mass spectrometry (MS) or tandem mass spectrometry (MS/MS)).

I warmly invite colleagues to submit their original contributions to this Special Issue, which will be of interest to a wide range of readers!

I would be delighted if you could respond to confirm your contribution and the proposed title by 15 July 2020 to assist in planning the whole project. In the cases of review articles, an additional brief (1–2 pages) description of the topic including a draft index is required. This preliminary step is essential to avoid overlapping of topics. The degree of novelty and the significance of the research will be scrutinized prior to peer-reviewing process.
