Manufacturing Quality Control of Basic Green 1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | UV-Vis Spectrophotometry | Quantifies alkaline green 1 concentration based on absorbance at characteristic wavelength (e.g., ~620 nm) using Beer-Lambert law. |
| Loss on Drying | Gravimetric (Oven Drying) | Measures mass loss after drying at specified temperature (e.g., 105 C) to determine volatile content including moisture and solvents. |
| Water Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water and Karl Fischer reagent (iodine, sulfur dioxide, base, alcohol). |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously quantifies trace heavy metals after acid digestion by measuring element-specific emission intensities in plasma. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Measures non-volatile inorganic residue remaining after high-temperature ignition (e.g., 500–600 C) following sulfuric acid treatment. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate; endpoint determined by silver ion-selective electrode potential change. |
| Sulfate Impurity | Gravimetric (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4 under controlled conditions and determines mass of dried precipitate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a standardized aqueous solution (e.g., 1% w/v) using calibrated pH electrode. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection at multiple wavelengths. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Quantifies iron after acid digestion by measuring absorption of specific atomic resonance line (248.3 nm) in air-acetylene flame. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after controlled tapping of a known mass in a graduated cylinder per ASTM D1895. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in intensity of laser light scattered by dispersed particles. |
