Manufacturing Quality Control of Pigment Red 3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | HPLC-UV | Quantifies Pigment Red 3 peak area against calibrated standard using reversed-phase chromatography and UV detection at ~500 nm. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature combustion and weighing of residual ash. |
| pH of Aqueous Extract | pH Meter Measurement | Measures hydrogen ion activity in aqueous suspension prepared under standardized dispersion conditions. |
| Residue on Sieve (45 um) | Dry Sieving | Determines particle size distribution by measuring mass retained on a 45 um stainless steel test sieve after mechanical sieving. |
| Color Strength (Relative Tint) | Reflectance Spectrophotometry | Compares reflectance curve and calculated tinting strength versus certified reference standard in standardized ink or PVC plastisol. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Simultaneously quantifies trace metal concentrations after acid digestion using plasma-excited atomic emission spectroscopy. |
| Organic Volatile Impurities | GC-MS | Identifies and quantifies residual solvents or synthesis by-products via gas chromatographic separation coupled with mass spectral detection. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely poured powder using standardized cylinder and tapping procedure. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Evaluates weight loss profile under controlled heating to assess decomposition onset temperature and thermal degradation behavior. |
| Lightfastness | Xenon Arc Weatherometer (ISO 105-B02) | Assesses color change after controlled exposure to xenon lamp irradiation simulating daylight, rated on ISO gray scale. |
| Migration Resistance | Solvent Extraction Test (ISO 2399) | Evaluates pigment bleed into adjacent polymer layers or media by measuring extractable colorant after solvent contact under defined time/temperature conditions. |
