Manufacturing Quality Control of 68516-73-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | HPLC-UV | Quantifies PY155 content by separation on reversed-phase column and UV absorbance detection at characteristic wavelength. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration using iodine-based redox reaction. |
| Residue on Sieve (45 um) | Dry Sieving | Determines particle agglomerate content by mechanical sieving and gravimetric analysis of retained material. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely poured powder using standardized cylinder and funnel apparatus. |
| Tinting Strength | Reflectance Spectrophotometry | Compares color strength relative to standard batch by measuring reflectance of ink or paint films under controlled conditions. |
| pH of Aqueous Extract | pH Meter Measurement | Evaluates acidity/alkalinity of aqueous suspension prepared per ISO 787-9, measured with calibrated pH electrode. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Simultaneously quantifies regulated heavy metals after acid digestion using plasma emission spectroscopy. |
| Ash Content | Gravimetric Analysis (Muffle Furnace) | Determines inorganic residue mass after ignition at 550 C in muffle furnace, reported as weight percent. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Color Value (CIE Lab*) | Spectrophotometry with D65 Illuminant | Quantifies color coordinates in CIE Lab* space using reflectance measurement against white tile under standard illuminant. |
| Organic Volatile Impurities | GC-MS | Identifies and quantifies residual solvents or synthesis by-products using gas chromatographic separation and mass spectral detection. |
| Thermal Stability (Onset Decomposition Temperature) | TGA | Determines temperature at which significant mass loss begins under controlled nitrogen atmosphere heating ramp. |
