Manufacturing Quality Control of ACID RED 26
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at lambda-max in standardized acidic medium using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Inorganic Ash | Gravimetric Analysis | Determines non-volatile residue after high-temperature incineration at 550-600 C. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities after acid digestion using plasma emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Measures chloride ions by titration with silver nitrate using silver indicator electrode. |
| Sulfate Content | Gravimetric Analysis | Precipitates sulfate as barium sulfate and determines mass after filtration and drying. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension (1% w/v) at 25 C. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance ratio against certified reference standard under identical conditions. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Particle Size Distribution | Laser Diffraction | Analyzes dispersed dry or wet sample to determine size distribution based on light scattering pattern. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder in standardized cylinder. |
| Residue on Ignition | Gravimetric Analysis | Determines volatile and non-volatile residue after ignition at 750 C for specified time. |
