Key Features：
- Strong anion exchange phase based on bonded amine-silane.
- Organic modifiers can be used on SAX columns.
- Sample retention can be controlled by varying pH, ionic strength, and the amount of organic modifier.
- The applicable pH range is 2.0-7.0.
- Provides high column efficiency and rapid analysis.
Applications：
- Environmental Analysis - Detection of anionic contaminants, inorganic ions, and organic acids.
- Pharmaceutical Industry - Separation of phosphate drugs, sulfonated compounds, nucleotides, etc.
- Food Safety Testing - Detection of additives, preservatives, and acidic flavorings.
- Biochemical Research - Purification of phosphopeptides, DNA/RNA fragments, and charged biomolecules.
