Manufacturing Quality Control of Vat Red 41
| 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 characteristic wavelength. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in presence of water and base. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550-600 C, representing inorganic impurities. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measuring absorbance of ground-state metal atoms in flame or graphite furnace vaporizer. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration using silver nitrate with silver electrode detection of endpoint based on formation of AgCl precipitate. |
| pH of Aqueous Suspension | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v, 25 C). |
| Solubility in Water | Visual Inspection & Filtration | Qualitative assessment of complete dissolution in specified volume of water at defined temperature, followed by filtration to detect insoluble residue. |
| Organic Impurities (Related Substances) | HPLC-DAD | Separation and detection of structurally related compounds using HPLC coupled with diode array detector for spectral confirmation. |
| Particle Size Distribution | Laser Diffraction | Measurement of scattered light intensity pattern from dispersed particles to calculate size distribution based on Mie theory. |
| Bulk Density | ASTM D1895 Method A | Determination of mass per unit volume of freely settled powder in a standardized cylinder. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Comparison of reflectance ratio (sample vs standard) at lambda-max in standardized pigment paste formulation. |
| Residual Solvents | GC-FID | Gas chromatographic separation followed by flame ionization detection to quantify volatile organic solvents remaining from synthesis or purification. |
