Manufacturing Quality Control of Solvent Yellow 98
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Ash Content | Gravimetric Analysis | Residue weight after incineration at 550 C in a muffle furnace, expressed as percentage of original sample. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy quantifies lead after acid digestion and matrix matching; conforms to ISO 17294-2. |
| Chlorinated Impurities | GC-ECD | Gas chromatography with electron capture detection identifies and quantifies chlorinated organic impurities using retention time and calibration. |
| pH of Aqueous Suspension | pH Meter Measurement | pH measured in 1% w/v aqueous suspension using calibrated pH electrode per ASTM D1193. |
| Particle Size Distribution | Laser Diffraction | Size distribution determined by Mie scattering theory analysis of laser light diffracted by dispersed particles in liquid medium. |
| Color Strength (Tinting Strength) | Visual Comparison or Reflectance Spectrophotometry | Relative color intensity assessed against standard batch using CIELAB coordinates or visual match under D65 illumination. |
| Organic Volatile Impurities | GC-FID | Identification and quantification of residual solvents and volatile organics using flame ionization detection and internal standard calibration. |
| Sulfated Ash | Gravimetric Analysis | Weight of residue after sulfuric acid treatment followed by incineration at 750 C, per USP <281>. |
| Bulk Density | Tap Density Measurement | Mass per unit volume determined by tapping a known mass in a graduated cylinder until volume stabilizes (ASTM D1895). |
| Residue on Ignition | Gravimetric Analysis | Weight loss upon heating at 800 C for 30 min; residue reported as % of initial mass, per EP 2.2.32. |
