Manufacturing Quality Control of Acid Red 92
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic wavelength (lambda max ~518 nm) using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water and iodine in a methanol-based reagent. |
| Inorganic Ash | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile residue after high-temperature incineration at 550-600 C. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities by measuring element-specific emission intensities in plasma. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration using silver nitrate and silver indicator electrode. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized 1% (w/v) aqueous solution at 25 C. |
| Water Solubility | Visual Dissolution Test | Assesses complete dissolution in distilled water at specified temperature (e.g., 20 C) within defined time. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities after ignition at 750 C for 30 min. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Sulphated Ash | Gravimetric Analysis | Measures ash content after treatment with sulfuric acid prior to ignition, indicating inorganic sulfate impurities. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder particles by analyzing angular scattering pattern of laser beam. |
| Colour Strength (Tinting Strength) | Comparative Visual or Instrumental Matching | Evaluates dyeing power relative to certified reference standard on standardized substrate (e.g., cotton fabric). |
