Manufacturing Quality Control of DIAMINE GREEN B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~620 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| 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 based on element-specific atomic emission intensities after acid digestion and plasma excitation. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures chloride ion concentration via silver nitrate titration using silver indicator electrode and endpoint detection. |
| pH of Aqueous Solution | pH Meter Measurement | Determines hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v) using calibrated glass electrode. |
| Water Solubility | Gravimetric Filtration and Drying | Measures undissolved residue after defined dissolution time and filtration, followed by drying and weighing. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds using reversed-phase column and UV detection at specified wavelength. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity patterns to calculate size distribution of dry or dispersed powder particles. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder in a standardized cylinder under controlled conditions. |
| Color Strength (Tinctorial Value) | Comparative Visual or Instrumental Matching | Compares dyeing performance against certified reference standard on standardized substrate under controlled dyeing conditions. |
| Residual Solvents (e.g., Methanol, Acetone) | GC-FID | Quantifies volatile organic solvents by gas chromatographic separation and flame ionization detection after headspace or direct injection. |
