Manufacturing Quality Control of Pigment Yellow 81
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (by HPLC) | HPLC-UV | Quantitative determination using reverse-phase chromatography with UV detection at characteristic wavelength (e.g., 420 nm) and external standard calibration. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Ash Content | Gravimetric Analysis (Incineration) | Residue mass after high-temperature incineration (550-600 C) followed by cooling and weighing to determine inorganic impurities. |
| pH of Aqueous Slurry | pH Meter Measurement | Measurement of hydrogen ion activity in a standardized 10% aqueous suspension using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering patterns from dispersed particles to calculate size distribution based on Mie theory. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Comparison of reflectance spectra (400-700 nm) against certified reference standard under D65 illumination and 10-degree observer. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Multi-element quantification after acid digestion using plasma excitation and optical emission detection at element-specific wavelengths. |
| Residue on Sieve (45 um) | Wet Sieving | Determination of coarse particles retained on a 45 um mesh sieve after controlled wet sieving and drying. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring sample into a calibrated cylinder and calculating density from weight and volume. |
| Volatile Organic Compounds (VOCs) | GC-MS | Separation and identification of volatile components by gas chromatography coupled with mass spectrometric detection. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Weight loss measurement as function of temperature (e.g., 100-300 C) under nitrogen to assess thermal decomposition onset and stability. |
| Water Soluble Salts | Conductivity Measurement | Quantification of ionic impurities via electrical conductivity of aqueous extract, correlated to NaCl equivalent concentration. |
