| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, intermediates, degradants) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, methanol, toluene) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based reagent stoichiometrically reacting with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, Pd) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfate Content | Ion Chromatography | Separates and quantifies sulfate ions using suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature ignition followed by precise weighing of residual residue. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against defined standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary method per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular scattering pattern of laser light passing through dispersed sample. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
