Manufacturing Quality Control of Acid Black 210
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Dye Content) | UV-Vis Spectrophotometry | Quantification based on absorbance at characteristic wavelength using a calibration curve with certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in pyridine-methanol medium. |
| Ash Content | Gravimetric Analysis | Residue mass after high-temperature incineration at 550 C, expressed as percentage of original sample weight. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements. |
| Chloride Ion | Potentiometric Titration with AgNO3 | Endpoint detection via silver-silver chloride electrode during titration with standardized silver nitrate solution. |
| Sulfate Ion | Gravimetric Analysis (as BaSO4) | Precipitation as barium sulfate followed by filtration, drying, and weighing of the precipitate. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Direct measurement using calibrated glass electrode in aqueous suspension at 25 C. |
| Water Solubility | Visual Inspection & Filtration | Assessment of complete dissolution in distilled water at specified temperature and concentration, followed by filtration to detect insoluble residue. |
| Organic Impurities (Related Substances) | HPLC-UV | Separation on reversed-phase column and quantification of impurities relative to main peak using UV detection at 254 nm. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution. |
| Bulk Density | Graduated Cylinder Method | Mass of sample freely poured into calibrated cylinder divided by its settled volume. |
| Thermal Stability | TGA | Mass loss monitoring under controlled nitrogen atmosphere from 25 C to 600 C at fixed heating rate. |
