| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Main Content (ZnDBC Purity) | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase. Detection is performed using a UV detector (typically at 230–254 nm). The content of ZnDBC is calculated by external standard method or area normalization method. |
| Zinc Content | Complexometric Titration (EDTA Titration) | The sample is dissolved in an acidic medium, pH is adjusted to an appropriate range, and titrated with standard EDTA solution using xylenol orange or Eriochrome Black T as indicator. Zinc content is calculated based on the volume of EDTA consumed. |
| Sulfur Content | Oxygen Flask Combustion-Iodometric Method or Elemental Analyzer | The sample is combusted at high temperature in an oxygen-filled flask to produce sulfur dioxide, which is absorbed by hydrogen peroxide and converted into sulfuric acid, followed by titration with standard iodine solution; alternatively, total sulfur content is directly determined using an elemental analyzer. |
| Free Amine (e.g., Dibutylamine) | Gas Chromatography (GC) | The sample is extracted with a suitable solvent, separated on a capillary GC column, detected by FID, and quantified by external standard method to determine residual free amine content. |
| Volatile Matter | Loss on Drying Method | A known amount of sample is dried in an oven at a specified temperature (e.g., 105±2°C) until constant weight. The volatile content is calculated from the mass loss. |
| Ash Content | High-Temperature Ignition Method | The sample is ignited in a muffle furnace at 550–600°C until constant weight. The percentage of residual inorganic matter relative to the original sample weight is reported as ash content. |
| Appearance and Color | Visual Color Comparison Method | Under natural light or standard illumination, the sample is visually compared with standard color solutions or a white reference plate to assess its color and appearance (typically pale yellow to amber powder or granules). |
| Melting Point | Capillary Melting Point Method | The sample is packed into a melting point capillary tube and heated at a specified rate in a melting point apparatus. The initial and final melting temperatures are recorded, and the melting range is evaluated against specifications (ZnDBC typically melts at 120–125°C). |
