Manufacturing Quality Control of Potassium L-aspartate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-Aspartic Acid Potassium Content) | Acid-Base Titration | Direct titration with standardized HCl solution using bromocresol green indicator; based on protonation of carboxylate groups. |
| Loss on Drying | Gravimetric Method (Thermogravimetry) | Mass loss measured after drying at 105 C for 2 hours under atmospheric pressure. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion and atomization in flame or graphite furnace. |
| Sulfated Ash | Gravimetric Method | Residue mass determined after incineration at 500-600 C following sulfuric acid treatment. |
| Chloride | Argentometric Titration (Mohr Method) | Titration with standard AgNO3 solution using potassium chromate indicator; forms AgCl precipitate. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 after acidification and addition of BaCl2; dried and weighed. |
| Iron | UV-Vis Spectrophotometry (1,10-Phenanthroline Method) | Formation of orange-red Fe(II)-phenanthroline complex measured at ~510 nm. |
| pH (1% aqueous solution) | Potentiometric Method (pH Meter) | Measurement of hydrogen ion activity using calibrated glass electrode in aqueous solution. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light by chiral L-aspartic acid moiety in solution. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separation on reversed-phase column with UV detection; quantification against reference standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination based on iodine consumption in pyridine-methanol reagent. |
| Microbial Contamination | Plate Count Method (Total Aerobic Microbial Count) | Enumeration of viable aerobic bacteria and fungi on soybean-casein digest agar after incubation. |
