Zodiac HST B mixed mode liquid chromatography column
Suitable for acidic, hydrophobic, and neutral analytes
The Zodiac HST B column is a high-performance, strongly alkaline mixed mode analytical column designed to separate multiple analytes. This column has alkaline ion pairing groups embedded on long ligand chains, which perform well in providing enhanced retention and selectivity, especially for hydrophobic and acidic components in complex mixtures. The pKa value is 10, and phenanthrene is often suitable for various chromatographic applications.
Why chooseZodiac HST BA pillar?
The Zodiac HST B column is an ideal choice for complex separation, providing high resolution, repeatability, and versatility for applications involving acidic and hydrophobic compounds. Its selectivity and compatibility with various mobile phases make it a handy choice for high-performance chromatography workflows.
Features:
1. Mixed mode separation: Combining reverse phase and anion exchange mechanisms to effectively separate acidic analytes and improve selectivity.
2. Eliminating silanol interactions: Strong bases, such as quaternary amines, typically have poor performance due to strong silanol interactions. The surface of the Zodiac HST B column is positively charged, eliminating these interactions and ensuring efficient separation and symmetrical peak shapes.
3. Dutt selectivity of alkaline compounds: Although alkaline compounds are retained through reverse phase interactions, the presence of positively charged groups on the analyte and stationary phase achieves Dutt selectivity through ion repulsion.
4. Optimal pH range: Operate within the pH range of 1.0 to 4.5, using acids such as trifluoroacetic acid, phosphoric acid, perchloric acid, or formic acid to control the mobile phase.
5. Wide mobile phase compatibility: Provides flexibility through multiple organic modifiers (0-100%) to regulate retention and selectivity.
6. Mobile phase compatibility: Fully compatible with LC-MS, preparative chromatography, and low UV detection applications.
