Manufacturing Quality Control of dipotassium malate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Potassium Malate Content) | Acid-Base Titration | Quantifies malic acid moiety by titration with standardized NaOH after acid hydrolysis and back-titration. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric reaction between water and Karl Fischer reagent. |
| pH (1% aqueous solution) | pH Potentiometry | Determines hydrogen ion activity using calibrated pH electrode in a 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Arsenic | Hydride Generation AAS (HG-AAS) | Converts arsenic to arsine gas, then measures atomic absorption after quartz cell atomization. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue mass after high-temperature combustion of sample in sulfuric acid medium. |
| Chloride | Potentiometric Titration with AgNO3 | Measures chloride ions by titration with silver nitrate using silver indicator electrode. |
| Sulfate | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Iron | UV-Vis Spectrophotometry (with 1,10-phenanthroline) | Forms colored ferroin complex; absorbance measured at ~510 nm for quantification. |
| Loss on Drying | Thermogravimetry (105 C, 2 h) | Measures mass loss after drying at specified temperature and time under controlled atmosphere. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects and enumerates aerobic microorganisms using selective media and colony formation. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity to determine size distribution of dry powder particles. |
