Manufacturing Quality Control of Acid Brown 75
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic wavelength using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration and weighing of residual ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies multiple heavy metals by measuring element-specific emission intensities in plasma. |
| Chloride Content | Potentiometric Titration | Determines chloride ions using silver nitrate titrant and silver/silver chloride indicator electrode. |
| Sulfate Content | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in standardized aqueous dispersion using calibrated pH electrode. |
| Water Solubility | Visual Filtration and Observation | Evaluates complete dissolution in specified volume of water at defined temperature and time. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Iron Content | AAS | Quantifies iron by measuring atomic absorption of light at specific wavelength in atomized sample. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely poured powder under standardized conditions. |
