Manufacturing Quality Control of DISPERSE BLACK 9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 580-620 nm based on peak area comparison with reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration (550-600 C) and subsequent weighing of the residual ash. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous dispersion using calibrated glass electrode and pH meter. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantifies total heavy metals by atomic absorption spectroscopy after acid digestion and matrix matching. |
| Sulfate Ash | Gravimetric Analysis | Determines sulfate-containing inorganic impurities by ignition of sample with sulfuric acid followed by ash weighing. |
| Residual Solvents (e.g., DMF, methanol) | GC-FID | Separates and quantifies volatile organic solvents using capillary GC with flame ionization detection and internal standard calibration. |
| Chloride Content | Argentometric Titration (Mohr method) | Titrates chloride ions with standardized silver nitrate solution using potassium chromate indicator for endpoint detection. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in aqueous suspension by analyzing angular dependence of laser light scattering. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of test solution to standard solution at lambda-max to determine relative dyeing power. |
| Water Solubility | Gravimetric Filtration | Determines insoluble fraction by dissolving sample in hot water, filtering through pre-weighed membrane, and drying/weighing residue. |
| Organic Impurities (Related Substances) | HPLC-DAD | Detects and quantifies structurally related degradation products and synthesis intermediates using HPLC with diode array detection. |
