| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component peak area relative to calibrated standard using flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized KOH solution using phenolphthalein indicator. |
| Density | Digital Density Meter | Measures oscillation period of a U-tube filled with sample, correlated to density via calibration. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at prism interface. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 430 nm. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver/silver chloride electrode to detect endpoint potential change. |
| Residue on Ignition | Gravimetric Analysis | Weighs non-volatile residue remaining after high-temperature ashing in a muffle furnace. |
| Viscosity | Rotational Viscometry | Measures torque required to rotate a spindle in sample at controlled temperature and shear rate. |
| Heavy Metals (as Pb) | ICP-OES | Atomizes and excites sample in argon plasma; detects characteristic emission wavelengths of metal elements. |
| Ethoxy/Methoxy Group Content | NMR Spectroscopy (1H NMR) | Quantifies integral ratios of characteristic proton signals from -OCH2CH3 and -OCH3 groups. |
| Hydrolytic Stability | Accelerated Aging Test + GC | Monitors degradation products and residual monomer after storage under controlled humidity/temperature conditions. |
