| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities based on retention time and UV spectral match relative to reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using flame ionization detection with headspace sampling. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Determines total elemental metals (e.g., Pb, Cd, Hg, As) after acid digestion by atomic emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature combustion in presence of sulfuric acid, followed by weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against white/black background. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume of freely settled powder using standardized cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode. |
