Manufacturing Quality Control of Direct Red 227
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Dye Content) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (approx. 510 nm) and calculates concentration using molar absorptivity and Beer-Lambert law. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Inorganic Salt (Na2SO4) Content | Gravimetric Analysis | Precipitates sulfate as BaSO4, filters, dries, and weighs to determine salt content by mass difference. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Digests sample and measures elemental emission intensities at characteristic wavelengths for multi-element quantification. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Uses calibrated glass electrode to measure hydrogen ion activity in a 1% w/v aqueous dye solution. |
| Water Solubility | Visual Inspection & Filtration | Determines solubility by dissolving specified amount in water at 25 C, observing clarity, and filtering residual insolubles. |
| Ash Content | Gravimetric Ignition | Heats dried sample at 550 C to oxidize organics; residue weight gives inorganic ash percentage. |
| Chloride Ion | Argentometric Titration (Mohr Method) | Titration with AgNO3 using K2CrO4 indicator; endpoint signaled by red Ag2CrO4 precipitate formation. |
| Substantivity (on Cotton) | Spectrophotometric Dye Uptake | Measures dye concentration difference in bath before/after exhaustion on cotton fabric using UV-Vis. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattered laser light intensity vs. angle to calculate volume-based particle size distribution. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates components on reversed-phase column; detects and quantifies impurities via UV absorption at 254/510 nm. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of powder in a graduated cylinder. |
