Manufacturing Quality Control of 18077-31-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Moisture Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Chlorine Content | Potentiometric Titration with AgNO3 | Precipitation titration where chloride ions react with silver nitrate to form AgCl, detected by silver indicator electrode potential change. |
| Acid Number | Acid-Base Titration with NaOH (in toluene/methanol) | Neutralization of acidic impurities (e.g., HCl, silanols) using standardized sodium hydroxide solution and phenolphthalein or potentiometric endpoint. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Sample is charred, sulfated with H2SO4, and ignited at 700-800 C; residue mass is measured after cooling in desiccator. |
| Heavy Metals (Pb, Cd, Cr, Hg, As) | ICP-MS | Multi-element quantification via ionization in plasma and mass separation/detection with high sensitivity and low detection limits. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Thermal equilibration of sample headspace followed by GC separation and mass spectral identification/quantification of low-boiling contaminants. |
| Viscosity | Capillary Viscometry (at 25 C) | Measurement of flow time through a calibrated capillary tube under gravity; kinematic viscosity calculated from time and calibration constant. |
| Density | Oscillating U-tube Densitometry | Determination based on resonant frequency shift of a vibrating U-shaped tube filled with sample, correlated to density via calibration. |
| Refractive Index | Refractometry (at 20 C) | Measurement of light refraction angle at air-sample interface using Abbe refractometer; correlates to molecular composition and purity. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at 455 nm. |
| Residual Solvents (e.g., toluene, hexane) | Gas Chromatography with FID | Separation and quantification of volatile organic solvents using headspace or direct injection and internal standard calibration. |
