| Ink Manufacturing | Manufacture of specialty writing inks or printing inks | Dissolved in water or solvent systems |
Manufacturing Quality Control of Fuchsin Acid
| 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. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine-methanol medium. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion; detection based on atomic emission intensity at element-specific wavelengths. |
| Arsenic Content | AAS (Hydride Generation) | Reduction of arsenic to arsine gas followed by atomic absorption measurement at 193.7 nm. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after ion exchange. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation as barium sulfate followed by filtration, drying, and weighing of the insoluble residue. |
| Residue on Ignition | Weight Loss on Ignition | Heating sample at 500-600 C to volatilize organic matter, then measuring inorganic ash residue by weight difference. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode immersed in saturated aqueous solution of the dye. |
| Solubility in Water | Visual Inspection and Filtration | Assessment of complete dissolution in specified volume of water at defined temperature, followed by filtration to detect undissolved particles. |
| Organic Volatile Impurities | GC-FID | Separation by capillary GC and detection via flame ionization for residual solvents and low-MW organics. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to derive size distribution of dispersed solid particles. |
| Color Strength (Tinting Strength) | UV-Vis Spectrophotometry | Comparison of absorbance ratio relative to a primary standard at lambda-max in standardized solution under controlled conditions. |
