“…In the case of the presented study, the authors have decided to conduct a discussion based primarily on the analysis of the obtained results. Similar studies on actual samples were also conducted by other authors [35][36][37][38][39]. The effects of the separation are presented in Table 2a-c and Figures 3 and 4.…”

We present the results of research on the optimal conditions for the separation and determination of newly obtained hypercoordinated compounds, which belong to the group of electrostatically stabilized silanates. The research involved five stationary and four mobile phases. The best selectivity was obtained using the graphite phase and the mobile phase consisting of acetonitrile/water (80/20). The maximum selectivity of the determined electrostatically stabilized silanates was 1.13 and 1.06 for (1), (2), (3); 1.10 and 1.15 for (4), (5), (6); and 1.12 and 1.15 for (7), (8), (9). The octadecyl phase (which is recommended as standard) did not yield satisfactory results.

This work presents a revision of the main applications of capillary electromigration methods in food analysis and Foodomics. Articles that were published during the period February 2019‐February 2021 are included. The work shows the multiple CE methods that have been developed and applied to analyze different types of molecules in foods. Namely, CE methods have been applied to analyze amino acids, biogenic amines, carbohydrates, chiral compounds, contaminants, DNAs, food additives, heterocyclic amines, lipids, secondary metabolites, peptides, pesticides, phenols, pigments, polyphenols, proteins, residues, toxins, vitamins, small organic and inorganic compounds, as well as other minor compounds. The last results on the use of CE for monitoring food interactions and food processing, including recent microchips developments and new applications of CE in Foodomics, are discussed too. The new procedures of CE to investigate food quality and safety, nutritional value, storage and bioactivity are also included in the present review work.

“…Numerous efforts have been made to develop analytical techniques for trace amounts antibiotics detection, such as highperformance liquid chromatography (HPLC), mass spectrum (MS) and capillary electrophoresis (CE) with low detection limit and high accuracy and precision. [8][9][10] There are also many new methods that have emerged with the development, such as colorimetry, uorescence, electrochemistry, chemiluminescence, electrochemiluminescence, photoelectrochemistry etc. [11][12][13][14][15][16][17][18][19] Fluorescence analysis is characterized by high sensitivity and selectivity.…”
