Manufacturing Quality Control of 31778-10-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (Main Component Content) | HPLC-UV | Quantifies pigment content by separation on a reversed-phase column and UV absorbance detection at characteristic wavelength (~500 nm). |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Residue on Ignition (Ash Content) | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic residue after controlled high-temperature combustion; mass difference reflects non-volatile ash. |
| Heavy Metals (Pb, Cd, Hg, Cr, As) | ICP-OES | Simultaneously quantifies trace metal impurities after acid digestion by measuring element-specific atomic emission intensities. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution based on angular dependence of laser light scattering by dispersed pigment particles in liquid medium. |
| Color Strength (Relative Tinting Strength) | Reflectance Spectrophotometry (with Standard White Tile) | Compares reflectance spectra of standardized pigment dispersions to reference standard; calculated as ratio of colorimetric values (e.g., CIELAB ΔE or relative tint). |
| pH of Aqueous Extract | Potentiometric pH Measurement | Determines acidity/alkalinity of aqueous suspension using calibrated pH electrode after defined extraction procedure. |
| Organic Volatile Impurities (e.g., residual solvents) | GC-FID | Separates and quantifies volatile organic residues using gas chromatography with flame ionization detection. |
| Bulk Density (Apparent & Tapped) | ASTM D1895 (Gravimetric Volumetric Method) | Measures mass per unit volume of powder under standardized conditions of pouring (apparent) or mechanical tapping (tapped). |
