| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies metals (e.g., Pb, Cd, Hg) by measuring absorption of characteristic wavelength light by ground-state atoms. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by silver nitrate titration using silver indicator electrode and reference electrode. |
| Acid Value | Acid-Base Titration with NaOH | Measures free carboxylic acid groups by titration with standardized sodium hydroxide solution using phenolphthalein. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral molecules in solution. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies structurally similar impurities using reverse-phase column and UV detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment to convert metals to sulfates. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Determines volatile content by weight loss after controlled heating under specified conditions. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
