Manufacturing Quality Control of CI 42500
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | UV-Vis Spectrophotometry | Quantifies main component based on absorbance at characteristic wavelength using Beer-Lambert law. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Measures mass loss after drying at specified temperature to determine volatile content. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Determines inorganic residue remaining after high-temperature ignition of sample. |
| Heavy Metals (as Pb) | AAS (Atomic Absorption Spectroscopy) | Quantifies total heavy metals by atomic absorption of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Argentometric Titration | Measures chloride ions via precipitation titration with standardized silver nitrate solution. |
| Sulfate Impurity | Gravimetric (Barium Sulfate Precipitation) | Determines sulfate as insoluble barium sulfate precipitate, followed by weighing. |
| Water Content | Karl Fischer Titration | Electrochemically quantifies water via iodine-sulfur dioxide reaction in anhydrous methanol medium. |
| Related Substances (Impurities) | HPLC (Reverse-phase) | Separates and quantifies structurally related impurities using C18 column and UV detection. |
| pH of Aqueous Solution | Potentiometric (pH Meter) | Measures hydrogen ion activity in aqueous suspension using calibrated glass electrode. |
| Color (APHA) | Visual Comparison or Colorimeter | Evaluates color intensity against platinum-cobalt standard scale for visual purity assessment. |
| Solubility in Water | Qualitative Gravimetric Test | Confirms complete dissolution in specified volume of water at defined temperature and time. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles by analyzing angular scattering pattern of laser beam. |
