Manufacturing Quality Control of Vat Green 8
| 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 620-640 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in methanol-pyridine medium. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550-600 C, expressed as percentage of original sample weight. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation as barium sulfate followed by filtration, drying, and weighing of the precipitate. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of residual solvents using capillary GC with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate size distribution. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of hydrogen ion activity in a standardized 1% w/v aqueous suspension. |
| Bulk Density | ASTM D1895 | Determination of mass per unit volume for freely flowing powder using calibrated cylinder and tapping procedure. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Comparison of reflectance ratio at characteristic wavelength against certified standard under controlled illumination. |
| Thermal Stability | TGA | Mass loss monitoring versus temperature ramp (e.g., 25-600 C at 10 C/min) to assess decomposition onset and residue. |
