Manufacturing Quality Control of 1,8-DIBROMONAPHTALENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID or GC-MS | Quantitative determination by comparison of peak area against a certified reference standard using gas chromatography with flame ionization or mass spectrometric detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents based on retention time and peak area calibration using headspace or direct injection GC. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system; endpoint detected amperometrically. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion, based on element-specific atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Mass measurement of non-volatile inorganic residue remaining after high-temperature ashing at 700-800 C. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against specified reference standards. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator; calculated as mg KOH per g sample. |
| Sulfated Ash | Gravimetric Analysis | Mass measurement of residue after combustion with sulfuric acid treatment followed by incineration at 700-800 C. |
| Organic Volatile Impurities (other than solvents) | GC-FID or GC-MS | Detection and semi-quantitative screening of low-level volatile organic contaminants using retention time matching and spectral library comparison. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dispersed solid samples. |
