Manufacturing Quality Control of Disperse Blue 79
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength, based on peak area comparison against reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine-based reagent, where water reacts stoichiometrically with iodine and sulfur dioxide. |
| Inorganic Ash | Gravimetric Analysis | Measures non-volatile residue after high-temperature incineration; ash weight reflects inorganic impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Simultaneously quantifies trace heavy metals by ionizing sample in plasma and detecting elemental ions via mass spectrometry. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions by titration with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Sulfate Content | Gravimetric Analysis (BaSO4 precipitation) | Precipitates sulfate as barium sulfate, filters and weighs dried precipitate to calculate sulfate concentration. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in 1% w/v aqueous dispersion using calibrated glass electrode pH meter. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Residue on Ignition | Gravimetric Analysis | Weighs residue remaining after controlled heating at 500-600 C, indicating volatile and combustible impurities. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares color intensity of standardized pigment paste against reference standard using reflectance at specified wavelength. |
| Organic Impurities (Related Substances) | HPLC-DAD | Separates and detects structurally related compounds using HPLC with diode array detection; identification and quantification based on retention time and spectra. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a known mass in a graduated cylinder. |
