Manufacturing Quality Control of Reactive Orange 1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 485 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent, measuring endpoint coulometrically or volumetrically. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 C) | Sample is incinerated to oxidize organic matter; residual inorganic oxides are weighed after cooling in a desiccator. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by ionizing sample aerosol in plasma and detecting elemental isotopes via mass spectrometry with high sensitivity and low detection limits. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration using silver nitrate solution with a silver/silver chloride electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Sulfate Impurity | Gravimetric Analysis (as BaSO4) | Sulfate ions precipitated as barium sulfate in acidic medium, filtered, dried, and weighed after ignition. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode and reference electrode. |
| Water Solubility | Gravimetric Filtration | Sample dissolved in boiling water, cooled, filtered hot, and undissolved residue dried and weighed to determine insoluble fraction. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles in liquid medium to calculate size distribution based on Mie theory. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Comparison of absorbance at lambda-max (485 nm) against a primary standard under standardized conditions to determine dyeing power. |
| Organic Impurities (Related Substances) | HPLC-DAD | Separation and detection of structurally related compounds using gradient HPLC with diode array detection for spectral confirmation and quantification. |
| Residual Solvents (e.g., Methanol, Acetone) | GC-FID | Volatile solvents extracted and quantified by gas chromatography with flame ionization detection using internal standard calibration. |
