Descrição geral
The removal of three carbohydrate moieties gives CHIROBIOTIC® TAG complementary selectivity to CHIROBIOTIC® T. Resolution is enhanced toward many of the amino acids, α, β, γ and cyclic, and especially sulfur-containing methionine, histidine and cysteine. A number of neutral molecules like the oxazolidinones, hydantoins and diazepines have shown enhanced resolution and, more remarkably, in the single solvents like methanol, ethanol and acetonitrile. Some acidic molecules have also shown increased selectivity.
- Bonded phase: Teicoplanin aglycone
- Operating pH range: 3.0 - 6.8
- Particle diameter: 5, 10 or 16 μm
- Pore size: 100 Å

We describe a new tandem-columns chiral-achiral HPLC arrangement by using a chiral column (CHIROBIOTIC TAG) connected in series with an achiral column (Spherisorb S5 SCX), based on a strong cationic exchange mechanism; this approach is very useful for the analysis

A direct chiral high-performance liquid chromatography (HPLC) method was developed and validated for the resolution and quantification of antiepileptic drug enantiomers, R-(-)- and S-(+)-vigabatrin (gamma-vinyl-gamma-aminobutyric acid) in pharmaceutical products. The separation was optimized on a macrocyclic glycopeptide antibiotic chiral stationary

Teicoplanin aglycone-based chromatography columns (Chirobiotic TAG) enable amino acid enantioseparation with aqueous mobile phases, which perfectly accommodates the distinct hydrophilicity of most amino acids. Therefore, this stationary phase constitutes a promising option in particular for preparative-scale separations that require high

The suitability of a teicoplanin-aglycone based chiral stationary phase for the simulated moving bed (SMB) enantioseparation of amino acids under enzyme-compatible conditions was shown following a procedure that is based solely on model-based simulations and HPLC experiments. A set of
