| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 7-methoxycoumarin content by UV absorbance at 320 nm using reverse-phase C18 column and external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., coumarin, 7-hydroxycoumarin) via gradient elution and peak area comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, toluene) using capillary column separation and flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Determines water content based on stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As) after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and high-temperature incineration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against white/black background under controlled lighting. |
| Solubility | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., ethanol, chloroform) by visual observation of clarity and residue after agitation. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser light. |
