| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies structurally similar impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., toluene, THF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol/pyridine medium. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions by suppressed conductivity detection after separation on anion-exchange column. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white-light illumination. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume of freely settled and tapped powder using standardized tapping procedure. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder via light scattering pattern analysis under controlled dispersion. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies weight loss upon heating under nitrogen to remove residual volatiles and moisture. |
