Zodiac HST C
Advanced Retention for Amines and Metal Ions
The Zodiac HST C column is a powerful mixed-mode analytical column designed for separating strong bases, di-bases, and amine compounds. With a pH of 3.5, this column offers unique interactions, including host-guest complexation with amino compounds and metal ions, providing enhanced selectivity and retention.
Why Choose Zodiac HST C Column?
The Zodiac HST C column offers a unique combination of complexation and reverse-phase interactions, making it ideal for separating amines, metal ions, and neutral compounds with enhanced selectivity.
- Host-Guest Complexation: Through Cation-Exchange Mechanism Improves retention of positively charged compounds, especially amines such as Primary and Secondary amine groups forming weak Host-Guest Complexes,
- Selective Retention of Amines: Retention order for amines: tertiary < secondary < primary.
- Reverse-Phase Retention: Retains neutral compoundswith high reproducibility and selectivity.
- Ion Selectivity: Alkali metals retained in reverse order: K+ < Na+ < Li+(distinct from classical ion-exchange).
- Mobile Phase Compatibility: Suitable for LC-MS, preparative chromatography, and low UV detection.
- pKa Value of 3.5: Optimized for the separation of amine compoundsand metal ions.
