| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 265 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient reversed-phase HPLC with UV detection; reported as area percent relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in methanol-based reagent; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric identity. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion; detection based on atomic emission intensity at element-specific wavelengths. |
| Residue on Ignition | Gravimetric Analysis | Weight loss measurement after high-temperature ashing (700-800 C); residue mass expressed as percentage of original sample. |
| Chloride Content | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; quantified using chloride calibration standards. |
| pH of Solution | Potentiometric Titration | Measurement of hydrogen ion activity in aqueous suspension using calibrated pH electrode; reported as pH value at specified concentration and temperature. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution in dispersed solid sample. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by visual observation of solid-to-liquid phase change in capillary tube under controlled heating rate. |
| Microbial Limits | Membrane Filtration | Quantitative recovery of viable microorganisms from sample solution by filtration, followed by incubation on selective agar media and colony enumeration. |
