的詳細介紹
AminoPac PA10 Amino Acid Column
For High-Resolution Separations of Free Amino Acids by AAA-Direct
The AminoPac® PA10 column is packed with a hydrophobic, polymeric, pellicular,
anion-exchange resin that is stable over the range of pH 0–14. The
unique pH stability allows the use of eluents that are conducive to
anodic oxidation of amino acids at gold electrodes. This column is
recommended for use with the AAA-Direct? Amino Acid Analyzer,
allowing direct detection of primary and secondary amino acids by IPAD,
with no need for pre- or postcolumn derivatization.
-
Derivatization not required
-
Carbohydrates and amino acids separated and detected simultaneously
-
Mid-femtomole to low-picomole detection limits
-
Compatible with all commonly used hydrolysis procedures
-
Can be configured for on-line analysis
AAA-Direct
is a technique that eliminates the need for any form of derivatization,
and is therefore compatible with on-line monitoring of cell cultures
and fermentation broths.
The AminoPac PA10 column is optimized
for separations of free amino acids by AAA-Direct. Vitamins, amino
sugars, and carbohydrates can be detected simultaneously with amino
acids. Additional capabilities include separation of a wide range of
sugars, phosphorylated amino acids, and common oxidation products of
sulfur-containing amino acids, such as cysteic acid, methionine sulfone,
and methionine sulfoxide.
