Separation of Nine Nucleotides with Core-Shell Mixed-Mode Column
Application description
Core-shell columns are able to handle higher flow-rates, while maintaining high efficiency and low back-pressure. Coresep SB was used to achieve separation of nine nucleotides. The strong embedded basic ion-pairing groups make it possible to separate compounds that don’t retain on reverse-phase columns.
Conditions of Experiment
Column: | Coresep SB |
Separation Modes: | reversed-phase, anion-exchange |
Column Dimenstions: | 4.6 x 150 mm, 5 um, 100A |
Mobile Phase: | 5% ACN, AmAc buffer (pH 4.5) gradient from 20 mmol to 300 mmol in 45 minutes |
Detection: | UV 270 nm |
Sample: | 0.3 mg/ml |
Injection: | 1 uL |
Flow rate: | 1.5 ml/min |
Analytes
Class of compounds: | Amino acid, Aromatic acid, Aromatic base, Nucleoside |
Nature of compounds: | Acidic, Basic, Hydrophilic, Polar |
Compounds: | Cytidine, Guanosine monophosphate, Guanosine diphosphate, Guanosine triphosphate, Adenosine |
