Manufacturing Quality Control of AZURE B EOSINATE PRACTICAL GRADE
| 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. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Measures weight loss after drying at specified temperature to determine volatile content. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Determines inorganic residue remaining after high-temperature ignition of sample. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies multiple heavy metals by measuring element-specific emission intensities in plasma. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures chloride ion concentration via silver nitrate titration using silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis (BaSO4 Precipitation) | Quantifies sulfate as insoluble barium sulfate precipitate after digestion and filtration. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in 1% w/v aqueous solution using calibrated pH electrode. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water content based on iodine generation and stoichiometric reaction with water. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and detects residual solvents using flame ionization detection with appropriate column and calibration. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
| Color Value (Tinctorial Strength) | UV-Vis Spectrophotometry | Compares absorbance of standardized dye solution against certified reference standard under defined conditions. |
| Microbial Contamination | Membrane Filtration and Plate Count | Quantifies aerobic mesophilic microorganisms by filtration, membrane transfer, and colony enumeration on nutrient agar. |
