Manufacturing Quality Control of POLYANETHOLESULFONIC ACID SODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (PAS content) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl after alkaline hydrolysis and back-titration. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and iodine in methanol/pyridine medium. |
| pH (1% aqueous solution) | pH Meter Measurement | Determines hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Sodium Content | ICP-OES | Quantifies Na+ by measuring characteristic atomic emission intensity after plasma atomization and excitation. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace heavy metals by mass spectrometric analysis of ionized atoms following acid digestion. |
| Chloride Impurity | Potentiometric Titration | Measures Cl- concentration using silver nitrate titrant and silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines content by weight of dried precipitate. |
| Residue on Ignition | Weight Loss on Ignition | Measures non-volatile inorganic residue after high-temperature ashing at 600-800 C. |
| Solution Clarity and Color | Visual Comparison | Evaluates clarity against water and color against standard platinum-cobalt scale in 1% solution. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies impurities using reversed-phase chromatography with UV detection at 254 nm. |
| Bulk Density | USP <616> Tap Density Method | Determines mass per unit volume after controlled tapping of a known powder mass in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
