| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Compares sample color to APHA platinum-cobalt standard scale using visual matching or absorbance measurement. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume based on oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature using calibrated Abbe refractometer. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporates known sample mass under controlled conditions and weighs residual solids after drying. |
| Total Sulfur Content | UV Fluorescence Detection (ASTM D5453) | Oxidizes sulfur compounds to SO2, then measures UV fluorescence intensity proportional to sulfur concentration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal ions after acid digestion by measuring absorption of element-specific wavelength light. |
| Residual Solvents | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates and identifies volatile organic impurities using retention time and mass spectral fragmentation. |
| Peroxide Value | Iodometric Titration | Measures peroxides via oxidation of iodide to iodine, followed by titration with standardized sodium thiosulfate. |
| Flash Point | Tag Closed Cup Tester (ASTM D56) | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under controlled conditions. |
