HPLC Separation of Amino Acids on Obelisc R Column
Closely related compounds like amino acids can be separated on an Obelisc R column by various buffers depending on the amount of baseline separation required. By choosing different buffers, the separation between compounds can be adjusted based on application needs, especially those that require low organic concentration in the mobile phase. UV detection at 250nm.
HPLC Separation of Phenylalanine, Glucosamine, and Tryptophan on Mixed-Mode Column
The Separation of Phenylalanine, Glucosamine and Tryptophan demonstrates how the small changes to the organic and/or buffer concentrations in the mobile phase affect the retention of compounds on a mixed-mode column by hydrophobic, ion-exchange and ion-exclusion mechanisms in reverse-phase HPLC chromatography. Evaporative Light Scattering Detector (ELSD) used
