Manufacturing Quality Control of Sodium L-aspartate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Aspartic Acid Sodium Content) | Acid-Base Titration | Quantifies sodium salt content by titration with standardized HCl after acid hydrolysis and back-titration. |
| Loss on Drying | Gravimetric Method (Thermogravimetry) | Measures weight loss after drying at 105 C to determine volatile matter and residual moisture. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light in solution. |
| pH (1% aqueous solution) | pH Potentiometry | Measures hydrogen ion activity using calibrated pH electrode in a defined aqueous solution. |
| Chloride (Cl-) | Argentometric Titration (Mohr method) | Quantifies chloride ions via precipitation titration with standard AgNO3 solution using K2CrO4 indicator. |
| Sulfate (SO42-) | Gravimetric Method (Barium Sulfate Precipitation) | Determines sulfate as insoluble BaSO4 precipitate after digestion and ignition. |
| Heavy Metals (as Pb) | Colorimetric Method (Thioacetamide) | Forms colored metal-sulfide complexes under controlled pH; compared visually or spectrophotometrically against lead standard. |
| Iron (Fe) | UV-Vis Spectrophotometry (1,10-Phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex measured at ~510 nm absorbance. |
| Arsenic (As) | Atomic Absorption Spectrometry (AAS) with Hydride Generation | Converts arsenic to arsine gas, then measures atomic absorption at 193.7 nm. |
| Residue on Ignition | Gravimetric Method (Sulfated Ash) | Measures non-volatile inorganic impurities remaining after high-temperature combustion. |
| Related Substances | High Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally related impurities (e.g., L-aspartic acid, sodium salts, degradation products) using UV detection. |
| Microbial Limits | Membrane Filtration / Plate Count | Determines total aerobic microbial count and absence of specified pathogens per pharmacopeial procedures. |
