Manufacturing Quality Control of Acid Green 25
| 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. |
| 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 and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities by measuring atomic emission intensities in plasma. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions using silver nitrate titrant and silver/silver chloride electrode. |
| Sulfate Impurity | 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 standardized aqueous suspension or solution. |
| Water Solubility | Visual Inspection & Filtration | Evaluates complete dissolution in specified volume of water at defined temperature and time. |
| 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 size distribution of dry powder by measuring angular variation in scattered laser light. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder in a standardized cylinder. |
| Thermal Stability (Onset Decomposition Temp) | TGA | Measures weight loss versus temperature to identify decomposition onset under controlled heating. |
