Manufacturing Quality Control of Fast Yellow G
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at characteristic wavelength. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after high-temperature incineration and weighing. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantifies lead and other heavy metals by atomic absorption spectroscopy. |
| Chloride Impurity | Potentiometric Titration | Measures chloride ions using silver nitrate titration with silver indicator electrode. |
| pH of Aqueous Suspension | pH Meter Measurement | Determines acidity/alkalinity of standardized aqueous dispersion using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution by measuring angular variation in laser light scattering. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares color intensity relative to standard via Kubelka-Munk transformed reflectance data. |
| Lightfastness | Xenon Arc Weatherometer Testing | Evaluates color change after controlled exposure to xenon arc radiation simulating sunlight. |
| Heat Stability | Thermogravimetric Analysis (TGA) | Measures weight loss under controlled heating to assess thermal decomposition onset. |
| Organic Volatile Impurities | GC-FID | Detects and quantifies residual solvents and volatiles using gas chromatography with flame ionization detection. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized mechanical tapping of sample in graduated cylinder. |
