DIAZ, Belinda et al. Adsorption chromatography to purify Spacer disaccharide of Active Pharmaceutical Ingredient of QuimiHib® vaccine . Vaccimonitor [online]. 2013, vol.22, n.1, pp.29-34. ISSN 1025-028X.

In this paper we study the conditions of adsorption chromatography on Silica gel 60 for purification of Spacer disaccharide a component of Active Pharmaceutical Ingredient (API) of QuimiHib® vaccine. For that, we made a scale down on an analytical scale that represented at 1.8% of industrial process, indicating reproducibility between two procedures in terms of packing efficiency, purity and recovery. Dynamic binding capacity of the resin Silicagel 60 by the DSE was roughly 125±0.2 mg /mL, 3.4 times the base process. The elution profile obtained, showed the possibility of collecting a unique fraction at range 195±2 and 260±2 minutes, if it is maintained a proper packing of the chromatography resin determined by asymmetry factor from 0.8 to 1.2, which ensures a recovery of 58.9±4.5% and high purity analyzed by Thin Layer Chromatography. Adjusting the adsorption conditions increases the productivity of chromatographic operation up to 3.5 fold, indicating that it is feasible in economic terms
