| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification via retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent; reaction stoichiometry enables precise water quantification. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry for sub-pptr sensitivity. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection following sample dissolution. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion with sulfuric acid treatment and high-temperature ignition; expressed as % w/w. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light source to confirm chiral integrity and enantiomeric purity. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine D10, D50, D90 values based on light scattering intensity vs. angle. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping per USP <616>; reported as g/mL for flow and handling assessment. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) using selective agar media and incubation. |
