| 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 detection of impurities using gradient elution and UV detection; identification and quantification based on relative retention times and response factors. |
| Residual Solvents | GC-FID | Volatile organic solvents are separated by capillary GC and quantified by flame ionization detection using internal standard calibration. |
| Moisture Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine reagent to determine water content based on the stoichiometric reaction between iodine, sulfur dioxide, and water. |
| Heavy Metals (Total) | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities of metal elements in plasma. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column followed by conductivity detection; chloride quantified using external calibration. |
| Residue on Ignition | Gravimetric Analysis | Mass of inorganic residue remaining after controlled high-temperature ashing of the sample, expressed as percentage weight. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid-to-liquid phase transition occurs, using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assessment of physical state, color, and homogeneity against defined specifications under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered light intensity from particles dispersed in air or liquid to calculate size distribution based on Mie theory. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a standardized aqueous suspension using a calibrated glass electrode system. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, used to assess chiral purity and identity. |
