Manufacturing Quality Control of Basic Violet 2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies main component concentration based on absorbance at characteristic wavelength using Beer-Lambert law. |
| Loss on Drying | Gravimetric Analysis | Measures mass loss after drying at specified temperature to determine volatile content including moisture and solvents. |
| Heavy Metals | ICP-OES | Detects trace metal impurities (e.g., Pb, Cd, Hg, As) by measuring elemental emission intensities in plasma. |
| Chloride Content | Potentiometric Titration with Silver Nitrate | Determines chloride ions via titration with AgNO3 using silver indicator electrode and endpoint detection. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous suspension or solution using calibrated glass electrode. |
| Water Solubility | Visual Inspection and Filtration | Evaluates complete dissolution in specified volume of water at defined temperature; residue assessed by filtration. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic impurities by weighing residue remaining after high-temperature incineration. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally similar impurities using reversed-phase chromatography and UV absorbance. |
| Iron Content | AAS | Measures iron concentration by atomic absorption of specific wavelength light after sample atomization in flame. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic sulfate content by ignition of sample with sulfuric acid followed by residue weighing. |
| Bulk Density | Tap Density Measurement | Measures mass per unit volume after controlled tapping of powder in calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution by measuring angular variation in intensity of laser light scattered by dispersed particles. |
