2 High-Performance Liquid Chromatography High-performance liquid chromatography (HPLC) is the most frequently used column chromatographic technique. Its popularity is caused by the high separation power, excellent selectivity, and the high diversity of solutes that Page 7 can be separated with this method. Similar to TLC, the majority of measurements are carried out either in normal or in reversed-phase separation mode using silica and modified silica supports. However, in contrast to TLC, reversed-phase HPLC (RP-HPLC) is a method of preference for the analysis of the majority of solutes.

Particle size 7-10 µm, PS-DVB with -NR3+ in the Cl-form). , particle size 5-8 µm, PS-DVB with -SO3- in the Ca-form). 4 mL/min. The collaborative study was simultaneously carried out by 19 official and private laboratories. 7. 7.  Reprinted from Reference [38] with permission.

This finding indicates that this HPLC method can be used for the determination of glucose, fructose, glycerol, and ethanol in wine.

The accuracy of the quantitative determination of the carbohydrate fractions separated by electrophoresis on supporting media is often low. Because of the high reproducibility, separation power, and rapidity, Page 12 HPLC is the method of preference for the separation of various carbohydrates. Since CE has similarsometimes betterseparation characteristics than HPLC, the more frequent application of CE in the carbohydrate analysis can be expected in the near future. The chromatographic analysis of carbohydrates may promote the determination of the authenticity and quality of various foods and food products.
