Manufacturing Quality Control of Pigment Red 49:1
| Detection Item | Common Detection Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with certified reference standard using reversed-phase chromatography and UV detection at 520 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550 C determined by weight difference before and after high-temperature ashing. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of metal ion concentration after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| pH of Aqueous Extract | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension (1% w/v, 25 C). |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Comparison of reflectance ratio (R457/R700) against primary standard using calibrated spectrophotometer. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents by gas chromatography with flame ionization detection. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder in a standardized cylinder. |
| Thermal Stability | TGA | Mass loss monitoring under controlled nitrogen atmosphere from 25 C to 600 C at 10 C/min heating rate. |
| Water Soluble Matter | Gravimetric Filtration | Determination of non-volatile residue after extraction with boiling water, filtration, and drying to constant weight. |
