Manufacturing Quality Control of AZOFUCHSIN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Acid Red 33 content) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max (approx. 508 nm) using Beer-Lambert law with reference standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 C) | Determines non-volatile inorganic residue after high-temperature incineration and weighing of residual ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace heavy metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via titration with silver nitrate using silver indicator electrode to detect endpoint potential shift. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of standardized aqueous dispersion using calibrated glass electrode pH meter. |
| Water Solubility | Visual Inspection & Filtration | Assesses complete dissolution in specified volume of water at defined temperature; undissolved residue is filtered and observed. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography with UV detection at 254/508 nm. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Quantifies Fe after sample digestion by measuring absorption of Fe-specific wavelength light in atomized flame. |
| Sulfate Content | Gravimetric Analysis (as BaSO4) | Precipitates sulfate as barium sulfate, filters, dries, and weighs the precipitate to calculate sulfate mass. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized cylinder and tapping procedure. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed powder suspension. |
