Manufacturing Quality Control of SOLVENT BLACK 5
| 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 reference standard calibration. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent, where water reacts stoichiometrically with iodine and sulfur dioxide in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Determines inorganic residue after high-temperature combustion; sample is ignited, cooled, and weighed to calculate percentage ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorption of specific elemental wavelengths by atomized sample; quantifies total heavy metals after acid digestion and matrix-matched calibration. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Uses silver nitrate titrant and silver indicator electrode; endpoint detected by abrupt potential change upon formation of AgCl 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 pH meter. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity pattern from dispersed particles to calculate size distribution based on Mie or Fraunhofer theory. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after controlled tapping of a graduated cylinder containing the powder; reported as g/mL. |
| Residue on Sieve (45 um) | Dry Sieving | Quantifies oversize particles retained on a 45 um stainless steel sieve after mechanical shaking under standardized conditions. |
| Sulfated Ash | Gravimetric Analysis (Ignition with H2SO4) | Sample treated with sulfuric acid before ignition to convert metals to stable sulfates; residue weighed after cooling. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic contaminants using capillary column and flame ionization detection with internal standard calibration. |
| Color Value (APHA) | Visual Comparison or Spectrophotometric APHA | Measures yellowness/brownness by matching sample solution color to platinum-cobalt standard scale or calculating APHA units from absorbance at 455 nm. |
