的詳細介紹
Dionex AminoTrap Column
The Thermo Scientific? Dionex? AminoTrap? is an in-line pretreatment column installed in place of the guard column, before a carbohydrate monosaccharide column.
-
In-line sample pretreatment column removes amino acids from samples for monosaccharide analysis.
-
Eliminates electrode fouling due to the presence of amino acids such as lysine.
-
Different dimensions are available for different monosaccharide analytical columns.
The
detection of monosaccharides and amine-containing glycoconjugates with
low levels of glycosylation can be compromised from fouling of the
working electrode by amino acids. Amino acids such as lysine are
potential interferents without the AminoTrap, because the oxidation
products inhibit detector response for later-eluting monosaccharides.
The
Dionex AminoTrap is an in-line pretreatment column installed in place
of the guard column, before an analytical carbohydrate monosaccharide
column, such as the Thermo Scientific Dionex CarboPac? PA20
or CarboPac PA10. Specifically designed with high selectivity for amino
acids, the Dionex AminoTrap column retains the amino acids, thus
allowing the monosaccharides to be eluted well before interfering amino
acids. In this way, the Dionex AminoTrap column eliminates working
electrode fouling for samples such as glycoprotein hydrolysates or food
sources that contain lysine.
The AminoTrap is packed with a 10 μm
particle size, high-capacity, anion-exchange resin that has high
selectivity for hydrophobic amino acids relative to monosaccharides when
using hydroxide eluents. The 4 × 50 mm Dionex AminoTrap is recommended
for use with the Dionex CarboPac PA10. The 3 × 30 mm Dionex AminoTrap is
recommended for use with the Dionex CarboPac PA20. The 0.4 x 35 mm
Dionex AminoTrap is recommended for use with the Dionex CarboPac PA10
(0.4 mm) and Dionex CarboPac PA20 (0.4 mm).
