Manufacturing Quality Control of HEPTAETHYLENE GLYCOL MONOMETHYL ETHER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies main component peak area relative to calibration curve using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine and water in anhydrous methanol medium. |
| Acidity (as Acetic Acid) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions at 455 nm wavelength. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature using sodium D-line (589 nm). |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume at 105 C and weighs non-volatile residue after drying to constant weight. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal ions by absorption of specific wavelength light after acid digestion and dilution. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects endpoint via silver electrode potential change during titration with silver nitrate. |
| Non-Volatile Matter | Gravimetric Analysis | Weighs residue after evaporation of sample under controlled conditions and drying to constant mass. |
| Flash Point | Closed Cup Tester (e.g., Pensky-Martens) | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized conditions. |
| Appearance | Visual Inspection | Assesses clarity and presence of suspended particles or phase separation against white background under controlled lighting. |
