Manufacturing Quality Control of ACID RED 88
| 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 with reference standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Inorganic Sulfate (as SO4) | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after drying and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal elements by measuring atomic emission intensities after high-temperature plasma atomization and excitation. |
| Chloride Impurity | Potentiometric Titration | Determines chloride concentration using silver nitrate titrant and silver indicator electrode detecting endpoint potential shift. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in standardized aqueous dispersion using calibrated glass electrode system. |
| Water Solubility | Visual Inspection and Filtration | Evaluates complete dissolution in specified volume of water at defined temperature; residue assessed after filtration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ignition at 500-600 C and weighing residual ash. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection at multiple wavelengths. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles in liquid medium. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume of powder after controlled tapping in standardized cylinder per ASTM D1895. |
| Color Strength (Relative to Standard) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample and certified reference at lambda-max to determine relative dyeing power. |
