Manufacturing Quality Control of 1,3-Dimethoxy-1,3-Dimethyl-1,3-Divinyl Disiloxane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibrated standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Abbe Refractometer | Measures ratio of speed of light in air vs. sample at specified temperature and wavelength (e.g., 589 nm). |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of a known sample mass under nitrogen at defined temperature. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride anions based on retention time and conductivity response relative to standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Atomizes and excites sample in argon plasma; detects element-specific emission wavelengths for semi-quantitative screening. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Extracts and separates volatile components from headspace vapor, identifies and quantifies via mass spectral library matching. |
| Viscosity | Rotational Viscometer | Measures resistance to flow under shear stress using rotating spindle immersed in sample at controlled temperature. |
| pH of Aqueous Solution | pH Meter with Glass Electrode | Determines hydrogen ion activity in 10% aqueous emulsion using calibrated combination electrode. |
