A Direct and Sensitive Analysis Method for Biogenic Amines in Dairy Products by Capillary Electrophoresis Coupled with Contactless Conductivity Detection

Derivatization‐free determination of aminoglycosides by CZE–UV in pharmaceutical formulations

“…Therefore, minor adjustments were necessary to restart the optimization procedure. Although HIBA and crown ether are often used to improve the separation of other analytes, such as amines [61–64], that was not the case for aminoglycosides. An electrolyte comprising solely of imidazole was chosen to restart the optimization procedure.…”

Contactless conductivity detection for analytical techniques: Developments from 2016 to 2018

“…Increased levels are indicators of microbial activity, which may result in food spoilage and health risks to the consumers. A rapid CE‐C 4 D method with minimum sample pretreatment was proposed for determination of histamine, putrescine, cadaverine, spermidine and tyramine in dairy products . Artificial sweeteners and acidulants/preservatives were monitored with a lab‐made CE‐C 4 D instrument (also suitable for portable operation) in various beverages and food samples in Vietnam .…”

Determination of biogenic amines in alcoholic beverages using a novel fluorogenic compound as derivatizing reagent

“…4, BAs determination in food is usually complicated because their concentrations are low, and the food samples usually need some pre-processing steps. Common methods for BAs determination are chromatographic ones, such as thin-layer chromatography (TLC), 6,7 capillary electrophoresis (CE), [8][9][10][11] gas chromatography (GC), [12][13][14][15][16] and high-performance liquid chromatography (HPLC). [17][18][19][20][21][22][23][24][25][26][27][28][29] HPLC is the most widely used because of its high resolution, sensitivity, efficiency, and reliability.…”
