Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Here we report A method recently developed concerning capillary electrophoresis (CE) separation of amino acid enantiomers with various commercially available cyclodextrins (CDs). In this method, Several experimental parameters were evaluated, such as CDs, the concentration and pH of the buffer, the separation temperature, and the separation voltage. Response surface methodology (RSM) was used to optimize the chiral separation conditions for tryptophan enantiomer. The results indicated that the optimal conditions for separation were: borate buffer in the concentration of 39.3 mmol/L, pH 9.5, β-CD 45 mmol/L, 25°C, separation voltage 20.0 KV and addition of lesser methanol.
