Manufacturing Quality Control of Disperse Red 11
| Detection Item | Common Analytical 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 500 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 in a muffle furnace, expressed as weight percent of original sample. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements. |
| Chloride Ion | Potentiometric Titration with AgNO3 | Titration using silver nitrate with silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of hydrogen ion activity in 1% (w/v) aqueous dispersion using calibrated glass electrode pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Comparison of absorbance ratio at lambda-max (approx. 500 nm) against a primary standard under standardized conditions. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents and volatile organics using capillary column gas chromatography with flame ionization detection. |
| Water Soluble Matter | Gravimetric Filtration | Mass of residue after extraction with boiling water, hot filtration, and drying at 105 C. |
| Bulk Density | Tap Density Measurement | Mass per unit volume after controlled tapping of a known mass in a graduated cylinder per ASTM D1895. |
| Thermal Stability | TGA | Weight loss measurement as function of temperature under nitrogen atmosphere to assess decomposition onset and residual char. |
