Manufacturing Quality Control of DISPERSE VIOLET 26
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 520-540 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in the presence of water and a base. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550-600 C, representing inorganic impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification by measuring characteristic atomic emission intensities after high-temperature plasma atomization and excitation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration using silver nitrate solution with a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| pH of Aqueous Suspension | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a standardized 1% w/v aqueous dispersion. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering patterns from dispersed particles to calculate volume-based size distribution. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents using capillary gas chromatography with flame ionization detection. |
| Substance Loss on Drying | Gravimetric Analysis | Mass loss measured after drying at 105 C for 2 hours, indicating volatile matter and residual moisture. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Comparison of absorbance ratio (sample vs. reference) at lambda-max in standardized dye solution, normalized to assay. |
| Residual Solvent (DMF) | GC-FID | Specific quantification of N,N-dimethylformamide using calibrated GC-FID with headspace sampling. |
| Water-Soluble Matter | Gravimetric Analysis | Mass of residue after extraction with boiling water, filtration, and drying, representing water-soluble impurities. |
