Manufacturing Quality Control of ANILINE BLUE (SPIRIT SOLUBLE)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~610 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in anhydrous methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomizes sample and measures absorption of specific wavelength light by ground-state metal atoms in flame or graphite furnace. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heats sample to 500-600 C to volatilize organic matter; residue weight reflects inorganic ash content. |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Uses calibrated pH electrode to measure hydrogen ion activity in aqueous suspension/dispersion of the dye. |
| Solubility in Ethanol | Visual Inspection / Filtration Test | Evaluates complete dissolution and clarity of 1% (w/v) solution in anhydrous ethanol after specified agitation and standing time. |
| Chloride Content | Argentometric Titration (Mohr Method) | Titrates chloride ions with standardized silver nitrate solution using potassium chromate indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Sulfate Content | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4 in acidic medium, filters, dries, and weighs the insoluble residue. |
| Iron Impurity | UV-Vis Spectrophotometry (with 1,10-Phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex; absorbance measured at ~510 nm for quantitative determination. |
| Substance Not Precipitated by Alcohol | Gravimetric Filtration | Dissolves sample in ethanol, adds water to precipitate impurities, filters, dries, and weighs residue. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of test solution to that of certified reference standard under identical conditions to determine relative dyeing power. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents or volatile organics using capillary column and flame ionization detection. |
