Manufacturing Quality Control of Triethylene Glycol Mono(2-propynyl) Ether
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or Hazen (APHA) Color Scale | Assessment of sample color intensity by comparing against platinum-cobalt standard solutions. |
| Density | Digital Density Meter | Measurement of mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface to infer purity and concentration. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass to dryness followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities via absorption of characteristic wavelength light by ground-state atoms in flame. |
| Chloride Content | Ion Chromatography (IC) | Separation and conductivity detection of chloride anions after ion exchange column elution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic impurities quantified by GC analysis of vapor phase above equilibrated sample. |
| Hydroxyl Value | Acetylation Titration | Esterification of hydroxyl groups with acetic anhydride, followed by back-titration of unreacted anhydride. |
