| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, toluene) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to determine water content via stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element determination of trace metals after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode to detect endpoint based on change in potential during AgCl precipitation. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under controlled temperature and vacuum conditions, indicating volatile and moisture content. |
| Residue on Ignition | Sulfated Ash Gravimetry | Weighing residue remaining after high-temperature incineration following sulfuric acid treatment to convert non-volatile inorganic impurities to sulfates. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate particle size distribution in dry or wet dispersion. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume of powder in a graduated cylinder before and after standardized tapping cycles per USP <616>. |
