Manufacturing Quality Control of CALCIUMPOLYSTYRENESULPHONATE
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample color and state (usually white to off-white powder or granules), with no visible foreign matter. |
| Identification Test | Infrared Spectroscopy (FTIR) | Confirm the structure using characteristic absorption peaks in infrared spectroscopy (e.g., sulfonic acid group ~1040 cm⁻¹, benzene ring ~1600 cm⁻¹). |
| Calcium Ion Qualitative Test | Add ammonium oxalate to form a white calcium oxalate precipitate, confirming the presence of calcium ions. | |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, and calculate the percentage weight loss to assess moisture and volatile content. |
| Residue on Ignition/ Ash Content | High-Temperature Ignition Method | Ignite the sample at high temperatures (e.g., 600–800°C) and determine the content of inorganic residue (mainly calcium sulfate, etc.). |
| Exchange Capacity (Ion Exchange Ability) | Acid-Base Titration Method | React the sample with excess hydrochloric acid to displace H⁺, then titrate the remaining acid with standard NaOH to calculate the exchange capacity per unit mass of resin (mmol/g). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine the content of heavy metal elements such as lead, arsenic, cadmium, and mercury after sample digestion, ensuring compliance with pharmacopoeia limits. |
| Chloride | Silver Nitrate Turbidity Method or Ion Chromatography (IC) | Determine free chloride ion content to evaluate residual chloride impurities from synthesis or purification processes. |
| Sulfate | Turbidity Method or Ion Chromatography | Detect free sulfate ions to assess by-product or degradation product content. |
| Microbial Limit | Microbiological Culture Method (Aerobic Bacteria, Mold/Yeast Count) | Perform microbial limit testing according to pharmacopoeia requirements to ensure compliance for non-sterile preparations. |
| pH Value | pH Meter Method | Prepare a suspension of specified concentration and measure its pH value (typically weakly acidic to neutral). |
| Particle Size Distribution | Sieve Analysis or Laser Particle Size Analyzer | Evaluate particle size distribution, which affects drug dissolution performance and oral palatability. |
| Organic Solvent Residues | Gas Chromatography (GC) | Detect residual organic solvents such as benzene, toluene, and xylene from the synthesis process, complying with ICH Q3C limits. |
