HPLC Separation of Histamine and Phenethylamine

Application Notes:
Application Columns:
Primesep® C is a mixed-mode HPLC column with reversed-phase, ion-exchange and host-guest complex formation properties. The Primesep C stationary phase combines a hydrophobic chain and an acidic functional group as a cation exchanger. Acids, bases, and neutrals can be retained and separated by Primesep 100 columns. Primesep C retains hydrophobic compounds by a reversed phase. Strongly polar and basic compounds such as quaternary amines are retained without the use of ion-pairing reagent by reversed phase and ion exchange. An unusual elution order compared to other HPLC columns is found for primary, secondary, and tertiary amines. Methods can be developed on Primesep Columns that are fully compatible with detectors such as UV, RI, conductivity, fluorescence, evaporative light scattering (ELSD) as well as mass spectrometers (LC/MS) and preparative chromatography (prep HPLC) systems.
Primesep® 200 is a mixed-mode HPLC column with general hydrophobic and ion-exchange properties. The Primesep 200 stationary phase combines a hydrophobic chain and a weakly acidic functional group as a cation exchanger. Acids, bases, zwitterions and neutrals can be retained and separated by Primesep 200 columns. Primesep 200 retains hydrophobic compounds by reversed-phase retention alone or a combination of reversed-phase and ion-exchange retention. Primesep 200 separates underivatized amino acids, amines, isomers and structurally related compounds by combining reversed phase and ion exchange. In this case the acidic functional group acts as an embedded ion-pairing reagent. Organic acids and diacids are separated by reversed phase and ion exclusion. Methods can be developed on Primesep Columns that are fully compatible with detectors such as UV, RI, conductivity, fluorescence, evaporative light scattering (ELSD) as well as mass spectrometers (LC/MS) and preparative chromatography (prep HPLC) systems.
