| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at characteristic wavelength. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after high-temperature incineration and subsequent weighing. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in standardized aqueous solution using calibrated glass electrode. |
| Water Solubility | Visual Inspection / Filtration | Assesses complete dissolution in specified water volume at defined temperature without visible residue. |
| Heavy Metals (as Pb) | AAS (Air-Acetylene) | Quantifies lead and other heavy metals by atomic absorption at element-specific wavelengths after acid digestion. |
| Chloride Content | Potentiometric Titration | Determines chloride ions via titration with silver nitrate using silver indicator electrode. |
| Substantivity (Dye Uptake) | Spectrophotometric Comparison | Compares color strength of dyed cotton fabric against standard reference using reflectance measurement. |
| Fastness to Light | ISO 105-B02 | Evaluates color change after controlled xenon arc exposure using gray scale assessment. |
| Fastness to Washing | ISO 105-C06 | Measures color change and staining on adjacent fabrics after standard washing cycle and drying. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of dry powder using angular scattering pattern of laser beam. |
| Residual Solvents (e.g., DMF, Methanol) | GC-FID | Quantifies volatile organic residues by gas chromatography with flame ionization detection. |
