| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| 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 against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary column and flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Determines total elemental metal impurities (e.g., Pb, Cd, Ni) after acid digestion by atomic emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid phase under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration against established reference standard. |
| Loss on Drying | Gravimetric Analysis | Measures mass loss after drying under specified temperature and vacuum conditions to assess volatile content. |
| Acid Value | Acid-Base Titration | Quantifies acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Phosphorus Content | ICP-OES | Determines total phosphorus concentration after sample digestion by measuring characteristic atomic emission line intensity. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume of freely packed powder after standardized tapping procedure. |
