Manufacturing Quality Control of Difurfuryl sulfide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Acid Value | 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 | Evaluation of yellowish discoloration by matching sample absorbance or appearance to APHA color standards. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Measurement of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of light bending angle at air-sample interface to infer molecular density and purity. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Weighing residue remaining after high-temperature ashing to quantify non-volatile inorganic impurities. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, based on absorption of characteristic atomic spectral lines. |
| Sulfur Content | Combustion-ICP-OES | Oxidative combustion followed by detection of sulfate-derived sulfur species using inductively coupled plasma optical emission spectroscopy. |
| Residual Solvents (e.g., ethanol, toluene) | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities quantified by equilibrium partitioning into headspace gas and GC-FID analysis. |
| Non-Volatile Residue | Evaporation-Gravimetry | Weighing residue after controlled evaporation of a known sample mass under specified temperature and vacuum conditions. |
| Odor Profile | Sensory Evaluation (Trained Panel) | Qualitative assessment of characteristic sulfurous odor intensity and off-note presence by certified sensory analysts. |
