Manufacturing Quality Control of Dibenzofuran
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies dibenzofuran content by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies chlorinated aromatic impurities based on molecular ion fragments and retention behavior. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter under controlled lighting. |
| Acid Value | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis | Quantifies inorganic residue after combustion with sulfuric acid treatment, reflecting mineral content. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling organic impurities by equilibrium partitioning into headspace followed by GC analysis. |
| UV Absorbance (275 nm) | UV-Vis Spectrophotometry | Evaluates optical purity and absence of conjugated impurities by absorbance measurement in specified solvent. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern analysis. |
