| 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 280 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient HPLC with UV detection; identification and quantification relative to main peak. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically with iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals | ICP-MS | Quantitative determination of trace metal elements (e.g., Pb, Cd, Hg, As) via plasma ionization and mass spectrometric detection after acid digestion. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content by high-temperature incineration followed by precise weighing of residual non-volatile matter. |
| Optical Rotation | Polarimetry | Determination of specific rotation using plane-polarized light passing through a solution; indicates enantiomeric purity and identity. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Direct measurement using calibrated glass electrode in aqueous suspension to assess acidity/basicity relevant to stability and handling. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens by filtration, membrane transfer to selective media, and colony counting. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder particle size via scattering pattern of laser beam, converted to volume-based distribution. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing temperature range at which solid-to-liquid phase change occurs under controlled heating. |
