| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color to APHA platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled conditions followed by weighing of non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride ions on an anion-exchange column and quantification via conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample decomposition by acid digestion followed by quantitative measurement of metal absorption at characteristic wavelength. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of sample under vacuum at elevated temperature and weighing of residual solids. |
| Aldehyde Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and semi-quantitation of aldehyde impurities using electron ionization and mass spectral libraries. |
