Manufacturing Quality Control of Acid Orange 3
| 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 485 nm. |
| Moisture Content | Karl Fischer Titration | Volumetric titration using iodine, sulfur dioxide, and pyridine in methanol to determine water content by stoichiometric reaction. |
| Ash Content | Gravimetric Analysis | Incineration at 550-600 C followed by weighing of residual inorganic material after complete organic matter removal. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions on anion-exchange column with conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element detection after acid digestion by measuring characteristic atomic emission wavelengths in inductively coupled plasma. |
| Sulfate Impurity | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode and pH meter in a saturated aqueous suspension (1% w/v). |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution. |
| Color Strength (Tinting Strength) | UV-Vis Spectrophotometry | Comparison of absorbance ratio (sample vs. standard) at lambda-max under standardized dilution and path length. |
| Solubility in Water | Visual Observation & Filtration | Assessment of complete dissolution in distilled water at 25 C with mechanical agitation and subsequent visual inspection and filtration. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue after heating at 750 C for 30 min to remove volatile matter and decompose organic components. |
