Manufacturing Quality Control of BIPHENYLDIMETHYLSILYL CHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using volatile organic compound separation and flame ionization detection. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separates and quantifies volatile solvents based on partitioning into headspace gas phase and chromatographic retention. |
| Moisture Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; detects element-specific emission wavelengths for multi-element quantification. |
| Acid-Value | Acid-Base Titration with NaOH standard solution | Neutralizes acidic impurities (e.g., HCl, silanols) using standardized sodium hydroxide solution and phenolphthalein endpoint. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color intensity against platinum-cobalt standard solutions using visual matching or absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determines mass per unit volume from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Abbe Refractometer | Measures bending angle of light passing through sample at specified temperature to determine refractive index. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporates solvent and volatile components under controlled conditions; weighs residual solids after drying. |
| Silanol Content | 1H NMR Spectroscopy | Detects and quantifies Si-OH protons by chemical shift integration relative to internal standard (e.g., TMS). |
| Residual Catalyst (e.g., Pd, Pt) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Ionizes sample in plasma and separates/quantifies trace metal isotopes with high sensitivity and mass resolution. |
