ALEXYS Carbohydrates Analyzer




Carbohydrates not only provide the most easily accessible energy source for our body, they also play an important role in many physiological processes. They are involved in intercellular recognition, infection processes, and certain types of cancer. Carbohydrates analysis is of interest to the food industry and also many fields in life sciences.

The ALEXYS Carbohydrates Analyzer based on HPLC with Pulsed Amperometric Detection (PAD) and its dedicated flow cells (FlexCell and SenCell) assure for most stable and sensitive routine analysis of carbohydrates, mono-, di- and polysaccharides, in samples like:

Application Notes

System configuration
