Use of complexing agents for selective separation in high-performance capillary electrophoresis

Enantioseparation of N-Dansyl-dl-amino Acids by Polyacrylamide Gel Zone Electrophoresis

“…In every case separated, L-isomer was found to migrate faster than D-isomer, thus confirming the previous results.s For good resolution, the minimal requirement of the concentration of /3-cyclodextrin was 50 mM; in this work, 70 mM of ,8-cyclodextrin was used (cf ref. 4).…”

Comparison of monolithic approaches for enantioselective capillary electrochromatography involving cyclodextrins

“…Earlier studies with neutral CD-containing gels for enantiomeric separation by CGE were carried out by Guttman et al [7], Cruzado and Vigh [55], and Lin et al [56].…”

“…In 1988, Snopek et al [6] described the first enantiomeric separations in capillary ITP using CDs as additives to the leading electrolyte. Also in 1988, CDs were incorporated into a gel matrix by Guttman et al [7] for enantiomeric separation in capillary gel electrophoresis (CGE). The use of CDs as chiral buffer additives in CZE was first described by Fanali [8].…”

Enantiomer Separation by Capillary Electrochromatography Using Fritless Packed Columns

“…Guttman et al 25 added β-cyclodextrin (β-CD) into the prepolymerization mixture of acrylamide (AAm), N,N′-methylenebisacrylamide (BIS) (5%T, 3%C) in a Tris-boric acid buffer (pH 8.3). With a 15 cm long column, about 100000 plates were generated for dansylated amino acids (Dns-AAs).…”
