| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities; endpoint detected potentiometrically or with phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Compares sample color to platinum-cobalt standard scale using APHA colorimeter or UV-Vis spectrophotometer. |
| Density at 20 C | Oscillating U-tube Densitometry | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through liquid sample at specified wavelength (e.g., sodium D line) to determine refractive index. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume under controlled conditions and weighs non-volatile residue after drying. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration with Ag electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelength after sample digestion. |
| Non-Volatile Matter | Gravimetric Analysis | Dries sample at 105 C to constant weight and measures residual solids mass. |
| Distillation Range | Capillary Column Distillation (ASTM D1078) | Measures initial boiling point, final boiling point, and % distilled at specified temperatures using standardized distillation apparatus. |
| Peroxide Value | Iodometric Titration | Quantifies peroxides by oxidation of iodide to iodine under acidic conditions, followed by thiosulfate titration. |
