Manufacturing Quality Control of HEXAETHYLDISILOXANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Moisture Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Determines acidic impurities by titration using phenolphthalein indicator and standardized sodium hydroxide solution. |
| Residue on Evaporation | Gravimetric Analysis | Measures non-volatile residue after controlled evaporation and drying under specified temperature and time. |
| Density at 20 C | Pycnometry or Digital Density Meter | Determines mass per unit volume using calibrated glass pycnometer or oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature to infer purity and composition. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; quantifies metal elements by characteristic emission wavelengths. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates volatile components by GC and identifies/quantifies them via mass spectral fragmentation patterns. |
| Color (APHA) | Visual Comparison or Spectrophotometric Method | Compares sample color to platinum-cobalt standard solutions using APHA scale or measures absorbance at 455 nm. |
| Peroxide Value | Iodometric Titration | Measures peroxides by oxidation of iodide to iodine, followed by titration with standardized sodium thiosulfate. |
| Non-Volatile Alkali (as Na2O) | Flame Photometry | Quantifies alkali metals by measuring characteristic emission intensity in flame after sample atomization. |
