| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator. |
| Hydroxyl Value | Acetylation followed by Acid-Base Titration | Esterification of hydroxyl groups with acetic anhydride, followed by back-titration of unreacted anhydride with NaOH. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Measurement of yellowness intensity by comparing sample absorbance or visual appearance to APHA color standards. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, using lead as the representative element and flame or graphite furnace AAS. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation titration where chloride ions react with silver nitrate, detected by silver ion-selective electrode. |
| Refractive Index | Refractometry at 20 C | Measurement of light bending angle through liquid sample relative to air, correlated to purity and composition. |
| Specific Gravity | Digital Density Meter or Pycnometer | Ratio of sample density to water density at specified temperature, used for identity and concentration verification. |
| Volatility Residue | Thermogravimetric Analysis (TGA) or Oven Drying | Mass loss determination after controlled heating to remove volatile components under inert or air atmosphere. |
