Manufacturing Quality Control of REACTIVE BLUE 4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Dye Content) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max in standardized solvent and pH. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Inorganic Salt (Na2SO4) | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metals after acid digestion using plasma-excited atomic emission. |
| pH of 1% Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode in standardized suspension. |
| Water Solubility | Visual Inspection & Filtration | Evaluates complete dissolution in distilled water at specified temperature and concentration. |
| Chromatographic Purity | HPLC with UV Detection | Separates and quantifies main dye peak versus impurities using reversed-phase C18 column. |
| Substantivity (on Cotton) | Reflectance Spectrophotometry | Measures color strength (K/S value) of dyed fabric relative to standard after controlled dyeing. |
| Fastness to Light | ISO 105-B02 | Evaluates color change after exposure to xenon arc lamp under controlled humidity and temperature. |
| Fastness to Washing | ISO 105-C06 | Assesses color change and staining after mechanical laundering under defined conditions. |
| Ash Content | Gravimetric Ignition | Determines inorganic residue mass after high-temperature incineration at 550 C. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder via scattering pattern analysis of laser beam. |
