Manufacturing Quality Control of DIMETHYLBIS(INDENYL)SILANE
| 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. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile impurities partitioned into headspace and quantified via GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separation and quantification of chloride anions based on ion exchange and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-MS | Multi-element detection by measuring metal ion mass-to-charge ratios after plasma atomization and ionization. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue remaining after high-temperature ashing at 550-600 C. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against standard reference under controlled lighting. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample to infer purity and composition at controlled temperature. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Quantifies weight loss upon controlled heating to assess thermal stability and volatile content. |
| Silicon Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Elemental silicon quantified by intensity of characteristic atomic emission lines after plasma excitation. |
