Manufacturing Quality Control of 631-36-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies tetraethylsilane peak area relative to internal/external standard using calibrated response factors. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HCl) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known sample mass at controlled temperature and weighs non-volatile residue. |
| Color | Visual Comparison or APHA Color Scale | Compares sample color against platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Digital Density Meter | Determines density by measuring oscillation period of a U-tube filled with sample at specified temperature. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at 20 C using calibrated refractometer. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals after acid digestion by detecting elemental emission spectra at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling impurities (e.g., ethanol, chloroform) by analyzing vapor phase above heated sample. |
| Non-Volatile Residue | Gravimetric Analysis | Same as Residue on Evaporation; reported separately per some specifications for trace organics. |
| Appearance | Visual Inspection | Assesses clarity and presence of suspended particles or phase separation in a clear glass container under transmitted light. |
