Manufacturing Quality Control of Acid Blue 129
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (approx. 620 nm) and calculates concentration using molar absorptivity and Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550 C) | Residue after high-temperature incineration is weighed to determine non-volatile inorganic impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element detection by measuring characteristic atomic emission spectra of plasma-excited elements. |
| Chloride Content | Potentiometric Titration with AgNO3 | Endpoint detected by silver electrode potential shift during precipitation of AgCl. |
| Sulfate Content | Gravimetric Analysis (BaSO4 precipitation) | Sulfate precipitated as BaSO4, dried and weighed to calculate sulfate mass fraction. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in standardized aqueous dispersion. |
| Water Solubility | Visual Inspection & Filtration | Sample dissolved in distilled water at 25 C; clarity and absence of undissolved residue assessed after filtration. |
| Organic Impurities (Related Substances) | HPLC-UV | Separation on reversed-phase column followed by UV detection to identify and quantify structurally related dye impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate size distribution by Mie theory. |
| Bulk Density | ASTM D1895 Method A | Mass of material freely poured into a calibrated cylinder divided by its volume. |
| Color Strength (Relative) | UV-Vis Spectrophotometry | Compares absorbance of sample solution to certified reference standard under identical conditions to determine relative dyeing power. |
