Manufacturing Quality Control of Pigment Red 146
| 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-sulfur dioxide reaction in pyridine-methanol medium. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration at 550-600 C followed by weighing of residual ash. |
| Residue on Sieve (45 um) | Wet Sieving | Evaluates particle agglomeration by washing sample through standardized 45 um mesh sieve and weighing retained material. |
| pH of Aqueous Extract | pH Meter Measurement | Measures hydrogen ion activity in aqueous suspension prepared under controlled conditions (e.g., 10% w/v, 25 C). |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Simultaneously quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver electrode to detect endpoint potential change. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of test solution to certified reference standard at lambda-max in standardized dispersion medium. |
| Lightfastness | Xenon Arc Weatherometer Test | Assesses color stability under controlled xenon lamp irradiation simulating daylight, rated per ISO 105-B02. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Evaluates weight loss profile during controlled heating (e.g., 25-300 C) to determine onset decomposition temperature. |
| Particle Size Distribution | Laser Diffraction | Measures volume-based size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Organic Volatile Impurities | GC-FID | Identifies and quantifies residual solvents or synthesis by-products using capillary column separation and flame ionization detection. |
