The SugarTrap column is an in-line sample pretreatment cartridge that removes carbohydrates from your amino acid sample.
In-line sample pretreatment cartridge eliminates laborious sample cleanup.
Removes carbohydrates from amino acid samples, ensuring reliable amino acid quantification.

AAA-DirectTM is a simple new approach for separating and detecting amino acids without derivatization. With this technique, it is possible to simultaneously separate and detect select carbohydrates with amino acids in a single run. For applications where carbohydrates are present when the analytes of interest are amino acids, the SugarTrap can be installed to remove the carbohydrates on-line.
The SugarTrap is an in-line pretreatment cartridge packed with cation-exchange resin. The amino acids are retained and the carbohydrates are washed to waste. After the carbohydrates have been removed from the cartridge, the SugarTrap is switched in-line with the AAA-Direct system and the AminoPac® PA10 column separates the amino acids. The examples below show the utility of the SugarTrap column from a variety of matrices.
