Manufacturing Quality Control of TETRAETHYLENEGLYCOL MONOMETHYL ETHER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area against calibrated standard curve using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color intensity to APHA platinum-cobalt standard scale using visual or spectrophotometric method. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Measures refractive index based on critical angle of total internal reflection at prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Weighs residue after controlled evaporation of specified sample volume under defined temperature and vacuum conditions. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal content by measuring absorption of characteristic wavelength light by ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration using silver nitrate and silver/silver chloride reference electrode. |
| Non-Volatile Residue | Gravimetric Analysis (Ignition Residue) | Measures residue mass after ashing sample at 550 degC in muffle furnace following sulfuric acid digestion. |
| Appearance (Clarity) | Visual Inspection in Nessler Tube | Assesses clarity and presence of suspended particles by visual examination against white background in standardized glass tube. |
| Flash Point | Closed Cup Pensky-Martens Tester | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under controlled closed-cup conditions. |
