“…When the charged CDs interact with racemic amino acids, the analytes migrate at a different velocity from a surrounding aqueous phase due to the electrophoretic migration of the ionic CDs. Although various anionic [34][35][36][37][38][39][40][41][42][43] and cationic CDs [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] are synthesized for CDEKC as summarized in Table 2, sulfated CDs (S-CDs) [34,35] and highly sulfated CDs (HS-CDs) [36][37][38][39][40][41] are still the predominant CSs due to their resolution powers and commercial-availability. Since commercially available S-CDs and HS-CDs from Beckmann Coulter are not single isomers but a mixture of sulfated CDs with a different degree of substitution (average; 9 and 12, respectively), a wide range of OTG, 1-S-octyl--d-thioglucopyranoside; DTDP, 3-(4,6-dichloro-1,3,5-triazinylamino)-7-dimethyamino-2-methylphenazine; LED-IF, light-emitting diode-induced fluorescence.…”
