Online StoreTrap Columns
Dionex offers three trap columns for bio applications to reduce sample preparation and ensure your successful chromatographic separation.
AminoTrap Column
The AminoTrap™ is an in-line pretreatment column installed in place of the guard column, before a carbohydrate monosaccharide column. The AminoTrap column retains amino acids in the sample, thus allowing the monosaccharides to be eluted free from interfering amino acids.
BorateTrap Column
The BorateTrap™ is a 4 × 50 mm column placed between the eluent pump and the injection valve to remove borate contamination from eluents used for HPAE-PAD. The BorateTrap eliminates peak tailing for mannose, fructose, and reduced monosaccharides, resulting from contamination of the eluent from borate and is highly recommended for optimal performance during carbohydrate analysis.
Carbohydrate Removal Cartridge
The Carbohydrate Removal Cartridge (CRC) is an in-line sample pretreatment cartridge that removes carbohydrates from your amino acid sample. The amino acids are retained on the cartridge as the carbohydrates are washed out to waste. The sugar-free amino acid samples are then transferred onto an AminoPac® PA10 anion-exchange column separated and detected by AAA-Direct™.
