Manufacturing Quality Control of ACID YELLOW 11
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantitative determination based on absorbance at characteristic wavelength (approx. 410 nm) using molar absorptivity and Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis (Weight Loss on Ignition) | Residue mass after high-temperature incineration (550-600 C) expressed as percentage of original sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of lead after acid digestion by measuring absorbance of ground-state atoms at specific wavelength (283.3 nm). |
| Water Solubility | Visual Dissolution Test | Qualitative assessment of complete dissolution in specified volume of distilled water at 25 C with gentle agitation. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode. |
| Chloride Impurity | Argentometric Titration (Mohr Method) | Titration with standard silver nitrate solution; endpoint detected by formation of red-brown Ag2CrO4 precipitate. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 after acidification and addition of BaCl2, followed by ignition and weighing of residue. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents or volatile organics using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to determine size distribution by Mie theory. |
| Color Strength (Tinting Power) | Reflectance Spectrophotometry | Comparison of color match against certified standard using reflectance measurements on pressed powder or dyed substrate. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measurement of mass loss versus temperature under controlled heating rate to assess decomposition onset and stability range. |
