| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Measures acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Quantifies non-volatile inorganic residue after high-temperature ashing at 600-750 C. |
| Heavy Metals | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Detects trace metal contaminants (e.g., Pb, Cd, Hg, As) by atomic emission intensity in plasma. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions based on ion exchange and conductivity response. |
| Specific Optical Rotation | Polarimetry | Measures optical activity using plane-polarized light rotation in a defined path-length cell at specified temperature and wavelength. |
| Refractive Index | Refractometry | Determines refractive index by measuring angle of light refraction at liquid-air interface using calibrated prism. |
| Boiling Point | Capillary Boiling Point Apparatus (ASTM D1120) | Observes temperature range at which sample transitions from liquid to vapor under atmospheric pressure. |
| Appearance | Visual Inspection (against USP <941> criteria) | Assesses physical state, color, and clarity in a transparent container under controlled lighting conditions. |
