Manufacturing Quality Control of ETHYL ORANGE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (~465 nm in alkaline medium) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Loss on Drying | Gravimetric (Thermogravimetry) | Determines volatile content by measuring mass loss after drying at 105 C for 2 hours under controlled conditions. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Quantifies non-volatile inorganic impurities by ignition of sample at 500-600 C and weighing residual sulfate ash. |
| Heavy Metals (as Pb) | Colorimetric (Thioacetamide Method) | Forms colored metal-sulfide complexes in acidic medium; compares intensity against lead standard solution. |
| Chloride Impurity | Potentiometric Titration (with AgNO3) | Measures chloride ion concentration via argentometric titration using silver nitrate and a silver indicator electrode. |
| Sulfate Impurity | Gravimetric (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4, filters, dries, and weighs to determine sulfate content. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in 1% w/v aqueous solution using calibrated pH meter with glass electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents (e.g., ethanol, acetone) using flame ionization detection. |
| Iron Impurity | UV-Vis (1,10-Phenanthroline Complexation) | Forms orange-red Fe(II)-phenanthroline complex; measures absorbance at ~510 nm for quantification. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric reaction with iodine, sulfur dioxide, and base in methanol medium. |
| Particle Size Distribution | Laser Diffraction | Measures scattered light intensity from dispersed particles to calculate size distribution based on Mie theory. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral impurities or degradation products in solution at specified concentration and wavelength. |
