Manufacturing Quality Control of Acid Black 1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max in standardized solvent system, using reference standard calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Inorganic Ash | Gravimetric Analysis (Ignition Method) | Measures non-volatile residue after high-temperature incineration of sample, followed by weighing of residual ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal elements after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver indicator electrode and endpoint detection via potential change. |
| Sulfate Content | Gravimetric Analysis (BaSO4 Precipitation) | Precipitates sulfate as barium sulfate under controlled conditions; mass of dried precipitate used to calculate sulfate content. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension or solution using calibrated glass electrode system. |
| Water Solubility | Visual Inspection & Filtration | Evaluates complete dissolution in specified volume of water at defined temperature, followed by filtration to detect insoluble residue. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection at appropriate wavelength. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Quantifies iron after acid digestion by measuring absorption of specific atomic resonance line at 248.3 nm. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Determines mass per unit volume of freely poured powder using standardized cylinder and tapping procedure. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dispersed particles in liquid medium based on angular dependence of scattered laser light intensity. |
