Manufacturing Quality Control of Solvent Black 34
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength (e.g., 620 nm) and external standard calibration. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Ash Content | Gravimetric Analysis | Residue mass after incineration at 550-600 C, expressed as percentage of original sample weight. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements in acid-digested sample solution. |
| Chlorinated Impurities | GC-ECD | Detection and quantification of chlorinated organic impurities using gas chromatography with electron capture detection. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v in distilled water) using calibrated pH electrode. |
| Solubility in Common Solvents | Visual Inspection/Filter Test | Qualitative assessment of complete dissolution and absence of undissolved particles or haze in specified solvents (e.g., toluene, xylene, DMF) at 25 C. |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Comparison of color intensity relative to certified reference standard via Kubelka-Munk transformed reflectance values at dominant wavelength. |
| Particle Size Distribution | Laser Diffraction | Determination of size distribution based on angular variation of laser light scattering from dispersed particles in liquid medium. |
| Volatile Organic Impurities | GC-FID | Separation and quantification of residual solvents and low-boiling impurities using gas chromatography with flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after sulfuric acid wet-ashing followed by high-temperature incineration, indicating inorganic sulfate-forming impurities. |
| Bulk Density | Tap Density Measurement | Mass per unit volume of powder after controlled tapping (ASTM D1895), reflecting packing behavior relevant to handling and dosing. |
