Manufacturing Quality Control of Pigment Red 48:1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity (main component) | HPLC-UV | Quantifies pigment content by separation on a 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 reagent in anhydrous methanol. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration (550-600 C) and weighing of residual ash. |
| pH of Aqueous Slurry | pH Meter Measurement | Measures hydrogen ion activity in a standardized water suspension (e.g., 10% w/w) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity to calculate volume-based particle size distribution in dispersed suspension. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares reflectance curve of test sample vs. reference standard in standardized oil or PVC millbase. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Quantifies elemental concentrations after acid digestion by measuring element-specific atomic emission intensities. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Chloride Ion Content | Potentiometric Titration | Measures chloride concentration via silver nitrate titration with silver/silver chloride indicator electrode. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder in a standardized cylinder under controlled conditions. |
| Thermal Stability | TGA | Evaluates weight loss profile under controlled nitrogen atmosphere to assess decomposition onset temperature. |
| Organic Volatile Impurities | GC-MS | Detects and identifies trace organic impurities based on retention time and mass spectral fragmentation patterns. |
