Manufacturing Quality Control of 141-62-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Separates components based on volatility and partitioning; quantifies main peak area relative to total chromatogram area. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in a methanol-based medium. |
| Acid Number | Acid-Base Titration | Determines acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Refractive Index | Refractometry | Measures bending of light through the sample at 20 C to assess purity and composition consistency. |
| Density | Oscillating U-tube Densitometry | Determines mass per unit volume by measuring resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standards; indicates presence of conjugated impurities or degradation products. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume at controlled temperature and pressure, then weighs non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Fe, Cu, etc.) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; measures element-specific emission wavelengths for multi-element quantification. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Extracts volatile compounds into headspace gas, separates by GC, and identifies/quantifies via mass spectral fragmentation patterns. |
| Flash Point | Closed Cup Pensky-Martens Tester | Determines lowest temperature at which vapors ignite under standardized closed-cup conditions. |
| Viscosity | Capillary Viscometry | Measures flow time of fixed volume through calibrated capillary tube under gravity to calculate kinematic viscosity. |
