Manufacturing Quality Control of Pigment Green 18
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (by assay) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~700 nm) and calculates concentration using Beer-Lambert law against certified reference standard. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Quantifies elemental concentrations after acid digestion by measuring element-specific emission intensities in plasma. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between water and iodine in a methanol-based reagent, monitored electrometrically. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic impurities by weighing sample before and after high-temperature ashing at 550-600 C. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity patterns to calculate size distribution based on Mie or Fraunhofer theory. |
| pH of Aqueous Slurry | Potentiometric pH Measurement | Determines hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents or organics by retention time and flame ionization detection. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares reflectance curve and relative color strength versus primary standard using standardized dispersion and drawdown. |
| Bulk Density | Tap Density Measurement (ASTM D1895) | Determines mass per unit volume after controlled tapping of a graduated cylinder containing the powder. |
| Sieve Residue (45 um) | Dry Sieve Analysis | Quantifies oversize particles retained on a 45 um woven wire mesh after mechanical agitation under standardized conditions. |
