Název v původním jazyce

Rapid Determinations of Saccharides in High-Energy Drinks by Short-Capillary Electrophoresis with Contactless Conductivity Detection

Popis výsledku v původním jazyce

The methodology for separations of saccharides in standard electrophoretic systems has been transferred to the short-capillary electrophoresis format. The laboratory-designed apparatus used employs a quartz capillary with an internal diameter of 10 mum,a total length of 10 cm and an effective length of 4 cm, in combination with contactless conductivity detection. It has been applied to separations of neutral mono- and disaccharides. The saccharides are separated in the anionic form, in solutions of alkali hydroxides, namely, KOH, NaOH and LiOH. The separation of a model mixture of five saccharides (sucrose, lactose, glucose, fructose and ribose) takes less than one minute, the LOD equaling 15, 35, 19, 17 and 24 mg L-1 and the LOQ equaling 52, 117, 63,53 and 79 mg L-1 for sucrose, lactose, glucose, fructose and ribose, respectively. The technique developed has been used to determine sucrose, glucose and fructose in high-energy drinks. The separation is finished within less than 50 s,
