Mixed-mode chromatography (MMC), or multimodal chromatography, refers to chromatographic methods that utilize more than one form of interaction between the stationary phase and analytes in order to achieve their separation. What is distinct from conventional single-mode chromatography is that the secondary interactions in MMC cannot be too weak, and thus they also contribute to the retention of the solutes. WebOne challenge that was anticipated in the separation of these molecules was the retention and peak shape of the nucleoside triphosphate. While separations have been achieved using ion-pairing reagents and HILIC mode chromatography, we chose to investigate the use of mixed-mode chromatography with ammonium acetate buffers to achieve a simple, fast … grand theft attorney florida
