Manufacturing Quality Control of Solvent Red 26
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against certified reference standard using reversed-phase chromatography and UV detection at ~530 nm |
| Related Substances | HPLC-DAD | Separation and identification of impurities by retention time and UV-Vis spectral matching relative to main peak |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine water content via stoichiometric reaction |
| Ash Content | Gravimetric Analysis (Ignition at 550 C) | Residue mass after high-temperature incineration, expressed as percentage of original sample weight |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of metal ions after acid digestion and matrix-matched calibration |
| Residue on Ignition | Gravimetric Analysis (Ignition at 700 C) | Mass of non-volatile residue remaining after ignition, indicating inorganic contaminants |
| Solvent Residues (e.g., acetone, toluene) | GC-FID | Separation and quantification of volatile organic solvents using capillary column and flame ionization detection |
| pH of Aqueous Suspension | pH Meter Measurement | Electrometric determination of hydrogen ion activity in a standardized aqueous slurry (e.g., 1% w/v in water) |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to derive volume-based particle size distribution in dispersed suspension |
| Bulk Density | Tap Density Tester (ASTM D1895) | Ratio of sample mass to its volumetric displacement after controlled mechanical tapping in a calibrated cylinder |
| Color Value (Redness) | CIELab Colorimetry (dE*ab) | Instrumental color measurement using reflectance spectroscopy and conversion to L, a, b* coordinates relative to standard white tile |
| Sulphated Ash | Gravimetric Analysis (H2SO4 treatment + ignition) | Sample treated with sulphuric acid before ignition; residue mass reflects inorganic sulphate-forming impurities |
