Manufacturing Quality Control of Chromeazurol B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic λ_max (≈605 nm) using Beer-Lambert law with reference standard. |
| Heavy Metals (as Pb) | ICP-OES | Measures total elemental metal content (e.g., Pb, Cd, Hg, As) after acid digestion by plasma-excited atomic emission. |
| Water Content | Karl Fischer Titration | Determines trace water via stoichiometric reaction between water and iodine in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures inorganic ash content by weighing sample before and after high-temperature (550–600 °C) ignition. |
| pH of Aqueous Solution (1% w/v) | pH Potentiometry | Measures hydrogen ion activity in standardized aqueous dispersion using calibrated glass electrode. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Quantifies chloride ions by titration with silver nitrate, detecting endpoint via silver ion-selective electrode. |
| Organic Volatile Impurities | GC-MS | Identifies and quantifies residual solvents (e.g., methanol, acetone) using gas chromatographic separation and mass spectral detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension by analyzing angular variation of laser light scattering. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance ratio of sample vs. certified reference standard under identical conditions to assess batch-to-batch dyeing performance. |
