Manufacturing Quality Control of METHACRYLOXYPROPYL TERMINATED POLYDIMETHYLSILOXANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative separation and detection of target compound based on volatility and retention time relative to reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine-sulfur dioxide reaction stoichiometrically proportional to water content. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Viscosity | Capillary Viscometry | Measurement of flow time through calibrated capillary tube under gravity, converted to kinematic viscosity using calibration constants. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated refractometer, correlated to composition and purity. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color intensity against platinum-cobalt standard scale using visual matching or absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature ashing of sample in platinum crucible. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals via flame or graphite furnace AAS after acid digestion and matrix matching. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver electrode to detect endpoint based on change in potential due to AgCl precipitation. |
| Density | Digital Density Meter | Measurement of oscillating U-tube frequency shift induced by sample density, calibrated with air and water standards. |
| Volatile Organic Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Qualitative and quantitative analysis of low-boiling impurities via thermal equilibration and mass spectral identification. |
| Hydrolyzable Chlorides | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions released after controlled aqueous hydrolysis of reactive Si-Cl bonds. |
