为了高分辨率分离游离氨基酸，请选择Thermo Scientific™Dionex™AminoPac™PA10氨基酸色谱柱。Dionex AminoPac PA10色谱柱填充有疏水，聚合，薄膜，阴离子交换树脂，该树脂在pH 0-14的范围内稳定。独特的pH稳定性允许使用有助于金电极上氨基酸阳极氧化的洗脱液。建议将该色谱柱与Thermo Scientific™Dionex™AAA-Direct™氨基酸分析仪系统一起使用，该系统可通过集成的脉冲安培检测（IPAD）直接检测一级和二级氨基酸，而无需柱前或柱后衍生化。

Optimized for Separation of Free Amino Acids by the Dionex AAA-Direct System

The Dionex AAA-Direct system eliminates the need for any form of derivatization, and is therefore compatible with on-line monitoring of cell cultures and fermentation broths. 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.

Engineered for Superior Chromatographic Performance

• 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

About Dionex AminoPac Amino Acid Columns

Thermo Scientific offers two approaches to amino acid analysis: anion-exchange separation by the Dionex AAA-Direct system, in which amino acids are detected directly without the need for derivatization; and anion-exchange separation with postcolumn derivatization.

• Dionex AminoPac PA10 columns separate free amino acids without the need for derivatization.

• Dionex AminoPac PA10 columns separate free amino acids with derivatization.

• Both columns are compatible with solvent, high pH, and high temperatures.

• Both columns facilitate easy scale-up.

Dionex AminoPac columns are used for high-resolution separations of free amino acids as well as for separation and detection of a wide range of sugars, phosphorylated amino acids, and common oxidation products of sulfur-containing amino acids.
