Manufacturing Quality Control of Direct Red 13
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 500 nm, comparing peak area to certified reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration (550-600 C) and subsequent weighing of residual ash. |
| pH of Aqueous Suspension | pH Meter Measurement | Evaluates acidity/basicity by measuring pH of a standardized suspension (e.g., 1 g/100 mL in distilled water) using calibrated pH electrode. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantifies total heavy metals by atomic absorption spectroscopy after acid digestion and matrix-matched calibration. |
| Residual Solvents (e.g., Ethanol, Toluene) | GC-FID | Detects and quantifies volatile organic solvents using gas chromatography with flame ionization detection and internal standard calibration. |
| Chlorinated Impurities (e.g., o-Chlorobenzoic Acid) | HPLC-UV | Separates and quantifies chlorinated aromatic impurities using reverse-phase HPLC with UV detection and reference standards. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry or dispersed powder using Mie scattering theory applied to laser light diffraction patterns. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder in a graduated cylinder under standardized tapping conditions. |
| Color Strength (Tinting Strength) | Visual Comparison or Reflectance Spectrophotometry | Compares color intensity against primary standard using gray scale or measures reflectance ratio at dominant wavelength (e.g., 490-510 nm). |
| Thermal Stability | TGA | Evaluates weight loss profile under controlled nitrogen atmosphere from 25 to 300 C to assess decomposition onset and residual volatiles. |
| Organic Volatile Impurities (Total) | GC-FID | Quantifies total volatile organics by headspace or direct injection GC-FID with response factor-corrected summation of detected peaks. |
