Manufacturing Quality Control of DEAE SEPHADEX
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Particle Size Distribution | Laser Diffraction | Measures scattered light intensity from suspended particles to calculate size distribution based on Mie or Fraunhofer theory. |
| Swelling Ratio | Gravimetric Method | Determines water uptake capacity by measuring weight difference between dry and fully swollen gel. |
| Functional Group Content (DEAE) | Acid-Base Titration | Quantifies tertiary amine groups via back-titration after ion exchange with standardized HCl. |
| Total Nitrogen Content | Kjeldahl Method | Converts organic nitrogen to ammonium sulfate by acid digestion, followed by distillation and titration. |
| Heavy Metal Impurities (Pb, Cd, Hg, As) | ICP-OES | Atomizes digested sample and measures element-specific emission intensities in plasma. |
| Residual Solvents (e.g., Ethanol, Acetone) | Gas Chromatography (GC-FID) | Separates volatile solvents using capillary column and detects them via flame ionization. |
| pH of Aqueous Slurry | Potentiometric Measurement | Measures hydrogen ion activity in 1% (w/v) gel suspension using calibrated pH electrode. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Flow Rate (Column Packing Performance) | Pressure-Flow Test | Evaluates hydraulic permeability by measuring linear flow velocity under defined pressure gradient in packed column. |
| Microbial Contamination | Membrane Filtration | Captures viable microorganisms from aqueous suspension on sterile membrane, followed by incubation and colony enumeration. |
| Chloride Ion Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection after ion exchange separation. |
| Crosslinking Degree (by Gel Fraction) | Solvent Extraction | Determines insoluble fraction after reflux extraction with water/ethanol to assess network integrity. |
