Manufacturing Quality Control of 1,1,3,3,5,5,7,7-OCTAMETHYLTETRASILOXANE

Detection Item Common Analytical Method Method Overview
Purity Gas Chromatography (GC) Separation and quantification based on volatility and column interaction; peak area comparison against reference standard.
Moisture Content Karl Fischer Titration Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous environment.
Acid Number Acid-Base Titration Neutralization of acidic impurities with standardized KOH solution using phenolphthalein or potentiometric endpoint detection.
Refractive Index Refractometry Measurement of light bending angle at air-sample interface, correlated to molecular composition and purity.
Density Digital Density Meter Oscillation frequency measurement of a U-tube filled with sample, converted to density via calibration.
Color (APHA) Visual Comparison or Spectrophotometry Comparison of sample color intensity against platinum-cobalt standards or absorbance at 455 nm.
Residue on Evaporation Gravimetric Analysis Evaporation of a known sample mass under controlled conditions followed by weighing of non-volatile residue.
Chloride Content Ion Chromatography (IC) Separation of chloride ions on an anion-exchange column with conductivity detection.
Heavy Metals (as Pb) Atomic Absorption Spectroscopy (AAS) Quantification of metal atoms by absorption of specific wavelength light after atomization in flame or graphite furnace.
Volatile Impurities Headspace Gas Chromatography (HS-GC) Analysis of low-boiling contaminants partitioned into headspace above heated sample, followed by GC separation.
Viscosity Capillary Viscometry Measurement of flow time through a calibrated capillary tube under gravity, converted to kinematic viscosity.
pH of Aqueous Extract pH Potentiometry Measurement of hydrogen ion activity in water extract using calibrated glass electrode and reference electrode.
