| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized NaOH solution using phenolphthalein indicator. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C for 2 hours to determine volatile content and moisture. |
| Residue on Ignition | Sulfated Ash Method | Determines inorganic impurities by ignition of sample at 700-800 C followed by gravimetric measurement. |
| Heavy Metals (as Pb) | Colorimetric Method (Thioacetamide) | Compares sample color intensity with lead standard after reaction with thioacetamide under controlled pH. |
| Chloride Impurity | Potentiometric Titration | Quantifies chloride ions by titration with silver nitrate using silver electrode detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Iron Impurity | UV-Vis Spectrophotometry | Measures absorbance of Fe-1,10-phenanthroline complex at ~510 nm after color development. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric reaction with iodine in pyridine-methanol medium. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular scattering pattern of laser beam through dispersed sample. |
