Manufacturing Quality Control of METHACRYLOXYPROPYL TERMINATED POLYDIMETHYLSILOXANE
| 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 coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic groups by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Viscosity | Capillary Viscometry | Measures kinematic viscosity by timing gravity-driven flow through a calibrated capillary tube at controlled temperature. |
| Refractive Index | Refractometry | Determines refractive index using total internal reflection principle at specified wavelength and temperature. |
| Density | Digital Density Meter | Calculates density from oscillation period of a U-tube filled with sample under controlled temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 430 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile residue mass after high-temperature ashing and cooling in desiccator. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies trace metals by measuring element-specific atomic emission intensities after plasma atomization and excitation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Volatile Organic Impurities | Headspace GC-MS | Identifies and quantifies low-boiling impurities by gas chromatographic separation coupled with mass spectrometric detection. |
| Refractive Index Temperature Coefficient | Refractometry at Multiple Temperatures | Calculates change in refractive index per degree Celsius based on measurements across a defined temperature range. |
