| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by HPLC with gradient elution and UV detection, relative to main peak area. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for identification and quantification of volatile organic solvents. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-methanol medium to determine trace water. |
| Heavy Metals | ICP-MS | Multi-element detection of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary method. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity (if applicable). |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering pattern to derive size distribution profile. |
| Bulk and Tapped Density | Tap Density Tester | Determination of mass per unit volume before and after mechanical tapping to assess flow and compaction behavior. |
