Manufacturing Quality Control of Basic Blue 11
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic lambda-max to quantify dye concentration via Beer-Lambert law using a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water content by coulometric or volumetric titration with iodine-based reagent in anhydrous methanol medium. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after complete combustion of organic matrix at controlled high temperature. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state atoms in flame or graphite furnace; quantifies total extractable heavy metals after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects endpoint via silver chloride precipitation using silver nitrate titrant and chloride-selective electrode. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized 1% w/v aqueous dispersion using calibrated pH electrode. |
| Solubility in Water | Visual Observation / Filtration Test | Assesses completeness of dissolution and clarity of solution after specified agitation and standing time per ISO 105-Z07. |
| Residue on Ignition | Gravimetric Analysis (Ignition at 550 C) | Same principle as ash content; reports non-volatile inorganic residue after high-temperature ignition. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents and low-MW organics using capillary column and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Measures scattering pattern of dispersed particles in liquid medium to calculate size distribution based on Mie theory. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Compares color difference (Delta E) of standardized dye/pigment paste against reference standard on white substrate. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after mechanical tapping of powder in calibrated cylinder per ASTM standard. |
