| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or indicator endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750 C in a platinum crucible, followed by weighing of inorganic residue after cooling in a desiccator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity against APHA platinum-cobalt standards or measurement of absorbance at 430 nm in a 10 mm cell. |
| Density at 20 C | Oscillating U-tube Density Meter | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Digital Refractometer | Determination of refractive index based on critical angle measurement of light passing from prism to sample interface. |
| Heavy Metals (as Pb) | ICP-OES after acid digestion | Quantification of total heavy metals following microwave-assisted nitric acid digestion and multi-element emission spectroscopy. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an ion-exchange column and quantitative detection via suppressed conductivity. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of a known volume at 105 C to dryness, followed by cooling and weighing of residual solids. |
| Aldehyde Impurities (e.g., acetaldehyde) | GC-MS with headspace sampling | Headspace extraction followed by separation and identification/quantification using mass spectral library matching and selected ion monitoring. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by organic peroxides in acidic medium, followed by titration of liberated iodine with standardized sodium thiosulfate. |
