Manufacturing Quality Control of Di(ethylene glycol) vinyl ether
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection of DGME based on retention time and peak area using a capillary column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent; endpoint detected amperometrically. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein indicator or potentiometric endpoint. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color to APHA platinum-cobalt standard solutions or measurement of absorbance at 430 nm in a 10 cm cell. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination of refractive index by measuring the critical angle of total internal reflection using a calibrated prism instrument. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass to dryness at 105 C followed by weighing of non-volatile residue. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride ions on an anion-exchange column with conductivity detection after elution with carbonate/bicarbonate buffer. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal impurities after acid digestion and chelation, using hollow cathode lamp and flame atomization. |
| Aldehydes (as Acetaldehyde) | Spectrophotometry (DNPH Derivatization) | Derivatization with 2,4-dinitrophenylhydrazine to form colored hydrazone, followed by absorbance measurement at ~450 nm. |
| Ethylene Oxide Residue | Headspace Gas Chromatography (HS-GC) | Thermal desorption of volatile EO from liquid sample into headspace, followed by GC separation and FID detection. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of sample under controlled nitrogen flow at 105 C until constant weight, then weighing of residual solids. |
