Fast separations of chiral β-blockers on a cellulose tris(3,5-dimethylphenylcarbamate)-coated zirconia monolithic column by capillary electrochromatography

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

“…However, the drawbacks of silica-based stationary phases are also well known, including a limited pH range of 2-8 in mobile phases due to unstable nature of Si O Si bond in acidic and basic solutions. Zou et al [30] and Park et al [31,32] coated CDMPC onto the hydrophilic poly(acrylamide-co-N,Nmethylene-bisacrylamide) monolith and porous zirconia monolith with confines of fused-silica capillaries for CEC enantioseparation, respectively.…”

In situ immobilization of a general resolving agent on the magnetic multi-wall carbon nanotube for the direct enantioenrichment of dl-mandelic acid

“…Many chiral selectors, including cyclodextrin, cellulose and macrocyclic antibiotics, have been used in enantioselective recognition [44][45][46][47][48][49]. Some amino acids were investigated as the selector in chiral electrochemical recognition [50,51].…”

Advances in monolithic silica columns for high-performance liquid chromatography

“…They separated colloidally dispersed nanoparticles with a back pressure of 5.8 MPa at a flow rate of 1 μL/min (Sakai-Kato, Ota, Takeuchi, and Kawanishi, 2011). Kumar et al performed a separation of eight chiral β-blockers on a cellulose tris(3,5-dimethylphenylcarbamate)-coated zirconia monolithic column by capillary electrochromatography (CEC), in less than a minute (Kumar and Park, 2011). Garcia et al demonstrated the separation of triacylglycerols in vegetable oils by CEC with UV-Vis detection within 12 min (Lerma-García, VergaraBarberán, Herrero-Martínez, and Simó-Alfonso, 2011).…”
