Manufacturing Quality Control of ACID BLUE 41
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max in standardized solvent system, using molar absorptivity or calibration curve. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent, where water reacts stoichiometrically with iodine and sulfur dioxide. |
| Inorganic Salts (Ash Content) | Gravimetric Analysis (Ignition Method) | Determines non-volatile residue after high-temperature ignition; ash mass reflects inorganic impurities including sodium sulfate and metal salts. |
| Heavy Metals (Pb, Cd, Cr, As, Hg) | ICP-OES | Simultaneously quantifies trace heavy metals after acid digestion by measuring element-specific atomic emission intensities in plasma. |
| Chloride Ion | Potentiometric Titration with AgNO3 | Measures chloride concentration via argentometric titration using silver nitrate and a silver indicator electrode or potentiometric endpoint detection. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of a standardized aqueous suspension or solution using calibrated glass electrode and reference electrode. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds (e.g., intermediates, isomers, degradation products) using reversed-phase chromatography and UV detection. |
| Solvent Residues (e.g., Methanol, Acetone) | GC-FID | Detects and quantifies residual solvents by gas chromatographic separation followed by flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular variation in laser light scattering intensity. |
| Bulk Density | Gravimetric Volumetric Method | Determines mass per unit volume of freely settled powder in a standardized cylinder under controlled conditions. |
| Color Strength (Relative to Standard) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample vs certified reference standard at lambda-max to assess batch-to-batch color intensity consistency. |
| Water Solubility | Visual Gravimetric Dissolution Test | Evaluates complete dissolution in specified volume of water at defined temperature and agitation time, followed by visual inspection and filtration if needed. |
