Manufacturing Quality Control of 1,3-DIETHYLTETRAMETHYLDISILOXANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to APHA platinum-cobalt standard scale using 10 mm pathlength cell at 455 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at sodium D-line wavelength. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of specified sample mass under nitrogen at defined temperature. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using suppressed conductivity detection after anion exchange separation. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content by atomization in flame and absorption of characteristic wavelength radiation. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling contaminants by equilibrium partitioning into headspace followed by GC-FID analysis. |
| Viscosity at 25 C | Capillary Viscometry | Determines kinematic viscosity from flow time through calibrated capillary tube under gravity at controlled temperature. |
| Flash Point | Closed Cup Pensky-Martens Tester | Measures lowest temperature at which vapors ignite momentarily when exposed to flame under standardized conditions. |
