Manufacturing Quality Control of Acid Red 27
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at λmax (≈505 nm) using a calibrated standard curve in specified solvent (e.g., water or aqueous buffer). |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities after acid digestion by measuring element-specific emission intensities in high-temperature plasma. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Determines chloride ion concentration via precipitation titration using silver nitrate and a silver indicator electrode; endpoint detected by potential inflection. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as BaSO₄ under controlled acidic conditions; mass of dried precipitate used to calculate sulfate content. |
| Water Content | Karl Fischer Titration | Measures trace water via stoichiometric iodine–sulfur dioxide reaction in anhydrous methanol/pyridine medium; coulometric or volumetric mode applicable. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a 1% (w/v) aqueous solution using a calibrated glass electrode system. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 500–600°C) | Determines non-volatile inorganic impurities by weighing residue remaining after high-temperature ashing of sample. |
| Organic Impurities (Related Substances) | HPLC with UV Detection | Separates and quantifies structurally related impurities (e.g., intermediates, isomers) using reversed-phase C18 column and UV detection at 254/505 nm. |
| Particle Size Distribution | Laser Diffraction | Analyzes dispersed dry or wet sample to determine volume-based particle size distribution by measuring angular scattering pattern of laser beam. |
| Color Strength (Relative to Standard) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample and certified reference standard under identical conditions to assess batch-to-batch dyeing performance consistency. |
