Recent advances of enantioseparations in capillary electrophoresis and capillary electrochromatography

Hybrid monolithic columns coated with cellulose tris(3,5-dimethylphenyl-carbamate) for enantioseparations in capillary electrochromatography and capillary liquid chromatography

“…Capillary-based microscale separation technique including capillary electrochromatography (CEC) and capillary liquid chromatography (CLC) is preferred in analytical scale of chiral separation due to low cost, speed, effectiveness and reproducibility [1][2][3][4][5][6]. The state-of-the-art in microseparation techniques has been reviewed, and it has been concluded that monolithic capillary columns are particularly suitable for both CEC and CLC because monolithic columns eliminate the need for frits retaining the stationary phase, and possess good permeability and good peak capacity [7][8][9][10][11][12].…”

Enantiomeric separation of some common controlled stimulants by capillary electrophoresis with contactless conductivity detection

“…CD and its derivatives are commonly used as the chiral selectors for the separation in CE [31,32]. When using conductivity detection it is necessary to keep the background conductivity of the buffer low, and thus neutral CDs, or species that are weak electrolytes and neutral at the pH used, have previously been employed for the separation of amines in their protonated form, and these have also been combined with the chiral crown ether (1)-(18-crown-6)-2,3,11,12-tetracarboxylic acid in order to achieve the required separation (18C6H 4 ) [22,[33][34][35][36].…”

Generalized model of electromigration with 1:1 (analyte:selector) complexation stoichiometry: Part I. Theory

“…strong, fully deprotonated acid) interacts with a mixture of selectors, which is often encountered in practice [4,[11][12][13][14][15][16][17][18][19][20][21][22][23]. Luire et al [24] have first described the interaction of a single analyte with two selectors as a simple extension of Eq.…”
