| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., acetone, methanol, toluene). |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Potentiometric Titration | Direct titration with silver nitrate using a silver indicator electrode; endpoint determined by potential inflection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, following USP <741> guidelines. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Mass loss measured after drying at 105 C for 2 hours under controlled humidity and airflow. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to quantify trace water content in the sample. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of non-volatile residue remaining after high-temperature incineration (600–700 C) followed by sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser diffraction to determine D10, D50, and D90 values. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of genotoxic impurities and residual solvents using gas chromatography-mass spectrometry with selective ion monitoring. |
