Manufacturing Quality Control of Solvent Violet 8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection for spectral confirmation and relative quantification. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750 C to combust organic matter, then weighing inorganic residue as sulfate ash. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at element-specific wavelengths. |
| Chlorinated Impurities | GC-ECD | Detection and quantification of organochlorine impurities using gas chromatography with electron capture detection. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid, charred, ignited at 750 C, and residual inorganic sulfate mass determined gravimetrically. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed suspension. |
| Bulk Density | Tap Density Measurement | Mass of powder divided by its volume after standardized mechanical tapping in a graduated cylinder. |
| pH of Aqueous Suspension | Potentiometric Measurement | Electrode-based measurement of hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v) at 25 C. |
| Solvent Residues | GC-FID | Quantification of residual manufacturing solvents using gas chromatography with flame ionization detection and external calibration. |
| Color Value (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness index or APHA color number using spectrophotometer at 430 nm or visual comparison to platinum-cobalt standards. |
