Manufacturing Quality Control of BIS(TRIETHOXYSILYL)METHANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and detection based on volatility and retention time. |
| Moisture Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol. |
| Acid Value | Acid-Base Titration | Determines acidic impurities by titration with standardized potassium hydroxide solution. |
| Ethoxy Content | Hydrolysis followed by Acid-Base Titration | Cleaves ethoxy groups to ethanol, then titrates liberated HCl after acid hydrolysis. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using ion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously detects trace metals by plasma excitation and element-specific emission wavelength measurement. |
| Color | Visual Comparison or Spectrophotometry | Evaluates color intensity against standard platinum-cobalt scale or absorbance at specified wavelength. |
| Density | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle at controlled temperature. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C using calibrated refractometer. |
| Viscosity | Rotational Viscometry | Quantifies resistance to flow under shear stress using spindle rotation in controlled temperature bath. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling contaminants by analyzing vapor phase above sample in sealed vial. |
