Description générale

Astec® CHIRALDEX G-TA is the first choice in the Group 1 CSPs (Surface Interactions, Complex Derivatives). This phase has been shown to be the most broadly-selective phase for the pharmaceutical industry, especially for the analysis of chiral intermediates and drug studies in various stages of clinical trials. Separations occur without the inclusion mechanism and are typically faster and more efficient than most chiral stationary phases. G-TA has also been used to separate parent drug enantiomers and their metabolites. G-TA has its highest selectivity for oxygen-containing analytes like alcohols, diols and polyols as the free alcohol and as an acyl derivative; amines as acyl derivatives; amino alcohols, halogens (Cl>Br>F), amino acids, hydroxy acids, lactones, furans and pyrans. It is also highly selective for halogenated compounds.

Application


  • Enantioselective gas chromatographic analysis of aqueous samples by on-line derivatisation. Application to enzymatic reactions.: This study explores the use of the Astec CHIRALDEX G-TA Capillary GC Column for enantioselective gas chromatographic analysis. The method involves on-line derivatization, enabling the analysis of aqueous samples and applying this technique to enzymatic reactions. This innovative approach highlights the column′s capability in achieving high selectivity and sensitivity for chiral compounds in complex matrices (Mommers et al., 2008).

Enzyme stability is an important parameter in biocatalytic applications, and there is a strong need for efficient methods to generate robust enzymes. We investigated whether stabilizing disulfide bonds can be computationally designed based on a model structure. In our approach
