Manufacturing Quality Control of Fluorescent brightener 85
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 345-365 nm, comparing peak area against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based solvent system. |
| Ash Content | Gravimetric Analysis | Incineration at 550-600 C followed by weighing of residual inorganic material after complete organic matter removal. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Measurement using calibrated glass electrode in a standardized aqueous dispersion at 25 C. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy after acid digestion; measures absorbance of ground-state atoms in flame or graphite furnace. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid prior to high-temperature incineration; residue weighed as sulfate-containing ash. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of volatile organic impurities using capillary GC with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles in liquid medium to determine size distribution. |
| Color Value (APHA) | UV-Vis Spectrophotometry | Measurement of absorbance at 430 nm in standardized solution, compared to APHA platinum-cobalt color scale. |
| Residue on Ignition | Gravimetric Analysis | Weight loss upon heating at 700-750 C; residue represents non-volatile inorganic contaminants. |
| Chloride Content | Argentometric Titration (Mohr Method) | Titration with silver nitrate in neutral solution using potassium chromate indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Bulk Density | Volumetric Method | Mass of sample divided by its freely settled volume in a standardized cylinder under controlled conditions. |
