Introduction: Gel filtration chromatography, also known as size-exclusion chromatography (SEC), is a vital technique in pharmaceutical analysis for separating molecules by size. B. Pharm students should understand how porous gel beads (e.g., Sephadex, Sephacryl) fractionate proteins, peptides, polymers, and drug aggregates without altering biological activity. Key applications include desalting, buffer exchange, removal of aggregates, molecular … Read more

Gel chromatography, also called size-exclusion chromatography (SEC) or gel filtration, separates molecules by size using porous stationary phases. This introduction explains the principle and theory—pore size, exclusion limit, partition coefficient (Kav), elution volume, void and total column volumes—and describes instrumentation such as columns, gels (Sephadex, agarose, polyacrylamide), pumps, detectors and fraction collectors. Practical considerations for … Read more

Ion exchange chromatography (IEC) is a fundamental separation technique in pharmaceutical analysis, widely used for drug purification, protein separation, and formulation development. B. Pharm students should learn about ion-exchange resins, strong and weak cation and anion exchangers, buffer selection, pH effects, selectivity, capacity, and elution strategies to apply IEC effectively in quality control, impurity removal, … Read more

Understanding factors affecting ion exchange — such as resin type, functional groups, exchange capacity, selectivity, pH, ionic strength, temperature, flow rate and bead porosity — helps B. Pharm students optimize the ion exchange process and methodology. Practical knowledge of column packing, regeneration, … Read more

Introduction: Ion exchange resins are crosslinked polymeric beads (commonly polystyrene‑divinylbenzene) bearing ionizable functional groups that exchange ions with surrounding media. Key properties include exchange capacity (meq/g), selectivity, degree of crosslinking, water uptake, kinetics, and stability. Mechanistically, ion exchange proceeds by reversible equilibrium influenced by charge, hydrated radius, pH, ionic strength, and Donnan effects. In pharmaceutics, … Read more
