| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative determination based on retention time and peak area comparison against certified reference standard. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures free chloride ions by argentometric titration using silver nitrate and a silver indicator electrode. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical determination of water content based on iodine generation proportional to water in the sample. |
| Acid Value | Acid-Base Titration with KOH | Neutralization of acidic impurities using standardized potassium hydroxide solution and phenolphthalein indicator. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection of sodium D-line light. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of a known sample mass under specified temperature and vacuum. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals via atomic emission spectroscopy after acid digestion and dilution. |
| Iron Content | ICP-OES | Specific quantification of Fe using characteristic emission lines following microwave-assisted acid digestion. |
