一般描述
去掉三个碳水化合物单体后，CHIROBIOTIC®TAG便有了CHIROBIOTIC®T互补选择性。对于许多氨基酸，α, β, γ环状，尤其是含有硫的蛋氨酸、组氨酸和半胱氨酸的分辨度增高。对于一些中性分子，比如恶唑烷酮、乙内酰脲类和二氮嗪，分辨度也增强了，尤其在单溶剂甲醇、乙醇和乙腈中效果显著。一些酸性分子选择性也增强了

This paper deals with the chiral separation of triiodothyronine (T3) and thyroxine (T4) by HPLC and micro-HPLC. The separation of T3 and T4 is of great pharmaceutical and clinical interest, since the enantiomers exhibit different pharmacological activities. The HPLC measurements

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

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

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
