Manufacturing Quality Control of Vat Orange 7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies main component concentration via absorbance at characteristic wavelength using Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Determines water content by electrochemical titration with iodine-based reagent in anhydrous methanol. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration and subsequent weighing. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized aqueous suspension using calibrated glass electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content after acid digestion by measuring atomic absorption at specific wavelengths. |
| Chloride Impurity | Potentiometric Titration | Determines chloride ions via titration with silver nitrate using silver/silver chloride electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as barium sulfate, followed by filtration, drying, and weighing. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Separates and quantifies residual solvents or volatile organics using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume by gently pouring sample into calibrated cylinder and measuring settled volume. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of test solution to certified reference standard under identical conditions. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile residue remaining after controlled heating at 500-600 C in muffle furnace. |
