Manufacturing Quality Control of DODECAETHYLENE GLYCOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 210 nm based on peak area comparison to reference standard. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated in situ, reacting stoichiometrically with water. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid impurities via titration with standardized NaOH solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation Titration | Determines total hydroxyl groups by acetylating with acetic anhydride, followed by back-titration of unreacted anhydride with NaOH. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing of the cooled crucible. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies trace metals (e.g., Pb, Fe, Ni) by plasma excitation and emission spectroscopy at element-specific wavelengths. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Refractive Index | Refractometry | Measures ratio of light velocity in air vs. sample at 20 degC using a calibrated Abbe refractometer. |
| Density | Oscillating U-Tube Densitometry | Determines mass per unit volume by measuring resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Flash Point | Closed Cup (PMCC) | Identifies lowest temperature at which vapors ignite momentarily under controlled conditions in a sealed test cup. |
| Gas Chromatographic Impurities | GC-FID | Detects and quantifies volatile organic impurities using capillary GC separation and flame ionization detection. |
