Manufacturing Quality Control of CYCLOTETRAMETHYLENEDIMETHYLSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component using retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based medium. |
| Acid Number | Acid-Base Titration | Determines acidic impurities by titration with standardized KOH solution using phenolphthalein indicator. |
| Color | Visual Comparison or Hazen (APHA) Scale | Evaluates color intensity by comparing sample to platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Determines refractive index based on angle of light refraction through the sample at specified wavelength and temperature. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of a known sample mass under inert atmosphere. |
| 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) | Detects trace metal elements by measuring characteristic atomic emission lines after plasma atomization. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies low-boiling impurities by analyzing vapor phase above heated sample. |
| Viscosity at 25 C | Capillary Viscometry | Determines kinematic viscosity by measuring flow time of fixed volume through calibrated capillary tube under gravity. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in aqueous extract using calibrated glass electrode system. |
