| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies total acidic groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Measures water via iodometric reaction where iodine is consumed stoichiometrically by water in methanol-based reagent. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standard solutions at 455 nm using calibrated spectrophotometer. |
| Acid Value | Acid-Base Titration | Determines mg KOH required to neutralize free acid groups in 1 g sample using ethanolic KOH and phenolphthalein. |
| Ester Content | Gas Chromatography (GC-FID) | Separates and quantifies methyl ester and related esters using capillary column and flame ionization detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C and subsequent weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomized metal vapor at characteristic wavelength. |
| Chloride Content | Potentiometric Titration | Determines chloride ions by titration with silver nitrate using silver electrode for endpoint detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic sulfate residue after sulfuric acid treatment and high-temperature incineration, then weighing. |
| Refractive Index | Refractometry | Measures ratio of light velocity in air vs. sample at 20 C using Abbe refractometer calibrated with distilled water. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Organic Impurities (Related Substances) | High-Performance Liquid Chromatography (HPLC-UV) | Separates and quantifies impurities using reversed-phase column and UV detection at 210 nm. |
