Manufacturing Quality Control of AZOCARMINE B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (~520 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomizes sample and measures absorption of characteristic wavelength light by ground-state metal atoms in flame or graphite furnace. |
| Arsenic | ICP-MS | Ionizes sample in plasma and detects arsenic isotopes (e.g., 75As) with high sensitivity and mass resolution. |
| Sulfated Ash | Gravimetric Analysis | Ignites sample at 700-750 C after sulfuric acid treatment; residue weight reflects inorganic impurities. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Uses silver nitrate titrant and silver indicator electrode to detect endpoint via abrupt potential change upon AgCl precipitation. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode system. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents (e.g., methanol, acetone) using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity pattern from dispersed particles to calculate size distribution based on Mie theory. |
| Color Strength (Tinting Strength) | Visual Comparison or Reflectance Spectrophotometry | Compares color match against certified reference standard under controlled D65 illumination; quantified as relative reflectance ratio. |
| Residual Solvent (Water) | Headspace GC | Equilibrates sample in sealed vial, injects headspace gas into GC for separation and FID detection of water vapor. |
| Microbial Contamination | Membrane Filtration and Plate Count | Filters sample through sterile membrane, places membrane on appropriate agar medium, incubates, and counts viable colony-forming units. |
