Manufacturing Quality Control of Acid Red 94
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic wavelength (e.g., ~510 nm) using Beer-Lambert law with reference standard. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content after acid digestion by quantifying atomic absorption of specific elemental wavelengths. |
| Arsenic Content | ICP-MS | Detects trace arsenic via ionization in plasma and mass-selective detection with high sensitivity and specificity. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine-sulfur dioxide reaction in anhydrous methanol medium. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode and pH meter. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic impurities by weighing residue remaining after high-temperature (750-800 C) incineration. |
| Chloride Content | Argentometric Titration (Mohr method) | Titrates chloride ions with standardized silver nitrate solution using potassium chromate indicator for endpoint detection. |
| Sulfated Ash | Gravimetric Analysis | Measures ash content after ignition with sulfuric acid pretreatment to convert metals to stable sulfates. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder via scattering pattern analysis of laser beam passing through dispersed sample. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after controlled tapping of a known mass in a graduated cylinder per ASTM D1895. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample vs. certified reference standard under identical conditions to assess dyeing power. |
