Manufacturing Quality Control of Acid Black 2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Acid Black 2 Content) | UV-Vis Spectrophotometry | Quantifies dye concentration based on absorbance at characteristic lambda-max in standardized solvent and pH. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and Karl Fischer reagent. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 C) | Determines non-volatile residue after high-temperature combustion and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace metal impurities by atomic emission from plasma-excited elements. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via silver nitrate titration using silver indicator electrode. |
| Sulfate Content | Gravimetric Analysis (as BaSO4) | Precipitates sulfate as barium sulfate and determines mass after filtration and drying. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous dispersion (e.g., 1% w/v, 25 C). |
| Water Solubility | Visual Inspection & Filtration | Evaluates complete dissolution in specified water volume at controlled temperature and time. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of sample solution to certified reference standard under identical conditions. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase chromatography and UV detection. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dispersed particles in liquid medium via light scattering pattern analysis. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after standardized tapping of a graduated cylinder containing the powder. |
