Manufacturing Quality Control of TRIETHYLENE GLYCOL MONOMETHYL ETHER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by separation and flame ionization detection relative to calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample color to platinum-cobalt standards or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter or Pycnometer | Measures mass per unit volume using oscillating U-tube principle or calibrated glass pycnometer. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using prism-based optical measurement. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation | Residue mass is determined by evaporating known sample mass to dryness and weighing the residue. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separates and quantifies chloride ions via conductivity detection or measures endpoint by silver nitrate titration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Quantifies total heavy metals after acid digestion by atomic absorption or optical emission of excited metal atoms. |
| Ethylene Glycol Impurity | Gas Chromatography (GC) with FID or Mass Spectrometry (GC-MS) | Separates and detects low-boiling glycol impurities using retention time and detector response. |
| Methanol Impurity | Gas Chromatography (GC) with FID | Separates and quantifies residual methanol based on retention time and calibrated peak area. |
| Aldehyde Content | Spectrophotometry after Reaction with Purpald Reagent | Measures aldehydes via formation of colored complex with purpald, quantified by absorbance at 550 nm. |
