| Inks | Blue colorant for solvent-based gravure and flexographic inks | Dissolved in organic solvents such as toluene, xylene, or ethyl acetate, then formulated with resins and additives into liquid ink |
| Coatings | Blue pigment component in automotive refinish coatings, wood coatings, and industrial baking enamels | Added to film-forming systems—e.g., alkyd or acrylic resins—after high-speed dispersion or sand milling |
Manufacturing Quality Control of Solvent Blue 59
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with certified reference standard using reversed-phase chromatography and UV detection. |
| Color Strength | UV-Vis Spectrophotometry | Measurement of absorbance at lambda-max in standardized solvent, correlated to a reference standard via Beer-Lambert law. |
| Solubility in Common Solvents | Visual Assessment | Qualitative evaluation of complete dissolution in specified solvents (e.g., toluene, xylene) at defined temperature and concentration. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in a reaction specific to water. |
| Ash Content | Gravimetric Analysis | Residue weight after incineration at 550 C in a muffle furnace, expressed as percentage of original sample mass. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy measuring absorbance of ground-state atoms in flame or graphite furnace after acid digestion. |
| Sulfated Ash | Gravimetric Analysis | Weight of residue after charring and sulfuric acid treatment followed by incineration at 750 C. |
| pH of Aqueous Extract | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in aqueous suspension prepared under standardized conditions. |
