Manufacturing Quality Control of 1066-40-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies triethylsilanol content by separation on a capillary column and flame ionization detection relative to an internal standard. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine generated electrochemically in the presence of water. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Evaluates non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co Scale) | Assesses color intensity by comparison to platinum-cobalt standards or absorbance at 455 nm. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C using calibrated refractometer. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies low-boiling organic impurities via retention time and mass spectral matching. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite under standardized closed-cup conditions. |
| Viscosity | Rotational Viscometry | Measures resistance to flow using a spindle rotating at controlled speed in sample at specified temperature. |
