Manufacturing Quality Control of ACID YELLOW 14 (C.I. 18960)
| 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. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature combustion and weighing of residual ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals by measuring element-specific emission intensities from plasma-excited atoms. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by monitoring potential change during silver nitrate titration using silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis (as BaSO4) | Precipitates sulfate as barium sulfate, followed by filtration, drying, and weighing. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode system. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering pattern of dispersed particles. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Measures mass per unit volume of powder after controlled tapping to achieve reproducible packing. |
| Color Strength (Tinting Strength) | Visual or Instrumental Comparison | Evaluates dyeing power relative to certified reference standard under standardized dyeing conditions. |
| Solubility in Water | Gravimetric Filtration Test | Assesses complete dissolution by filtering undissolved residue and weighing after drying. |
