Manufacturing Quality Control of Pigment Red 170
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | HPLC-UV | Quantifies pigment red 170 peak area relative to calibrated standard using reversed-phase chromatography and UV detection at ~500 nm. |
| Color Strength | Reflectance Spectrophotometry | Compares Kubelka-Munk absorption coefficient of sample dispersion to reference standard under standardized illumination and geometry. |
| Particle Size Distribution | Laser Diffraction | Measures angular scattering intensity of dispersed particles in liquid medium to calculate volume-based size distribution. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generated electrochemically in pyridine-methanol solvent. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Measures inorganic residue mass after high-temperature combustion of organic matrix in muffle furnace. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Quantifies elemental concentrations by measuring characteristic atomic emission intensities after acid digestion and plasma excitation. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separates and detects volatile organic impurities (e.g., toluene, xylene) using capillary column and flame ionization detection. |
| pH of Aqueous Extract | Potentiometric Measurement | Determines acidity/alkalinity of water extract using calibrated pH electrode under standardized suspension conditions. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Evaluates weight loss profile under controlled nitrogen atmosphere up to 300 C to assess thermal decomposition onset. |
| Lightfastness | Xenon Arc Weathering Test | Exposes coated panels to controlled xenon lamp irradiation with humidity and temperature cycles; rated per ISO 105-B02 grayscale. |
| Oil Absorption | ASTM D281 (Gum Arabic Paste Method) | Measures grams of linseed oil required to form a stiff paste with 100 g pigment, indicating surface area and dispersibility. |
| Bulk Density | ASTM D1464 (Tapped Density) | Determines mass per unit volume after standardized mechanical tapping of powder in graduated cylinder. |
