Manufacturing Quality Control of COBALT(II) PHTHALOCYANINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (CoPc content) | UV-Vis Spectrophotometry | Quantifies cobalt phthalocyanine concentration based on characteristic absorbance at lambda-max (~670 nm) using a calibrated standard curve. |
| Cobalt content | ICP-OES | Measures total cobalt concentration after acid digestion by detecting element-specific emission wavelengths in plasma. |
| Moisture content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Residue on ignition | Gravimetric analysis (weight loss on heating) | Measures non-volatile inorganic impurities by weighing sample before and after high-temperature ashing at 550-600 C. |
| Heavy metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace heavy metals after microwave-assisted digestion using mass-to-charge ratio separation and high-sensitivity detection. |
| Chloride content | Potentiometric titration with AgNO3 | Quantifies chloride ions by titration with silver nitrate, monitored by silver electrode potential change at endpoint. |
| Sulfate content | Gravimetric analysis (BaSO4 precipitation) | Precipitates sulfate as barium sulfate; quantified by drying and weighing the insoluble precipitate. |
| pH of aqueous suspension | pH meter measurement | Measures hydrogen ion activity in a standardized aqueous slurry (e.g., 1% w/v) using calibrated glass electrode. |
| Particle size distribution | Laser diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles in liquid medium. |
| Organic volatile impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents and organics using capillary column and flame ionization detection. |
| Bulk density | ASTM D1895 method A (tapped density) | Measures mass per unit volume after controlled tapping of a graduated cylinder containing the powder sample. |
| Color value (Delta E vs. standard) | Reflectance spectrophotometry | Calculates color difference (Delta E) from CIELAB coordinates measured on pressed pellet relative to certified reference standard. |
