Manufacturing Quality Control of ethylene dimethanesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies DMSO-Et content by separation and flame ionization detection relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Determines total acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Chloride (Cl-) | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate (SO42-) | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 under controlled pH and temperature, followed by filtration and weighing. |
| Appearance | Visual Inspection | Assesses clarity and color against water-white standard in a transparent glass container under controlled lighting. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using Abbe refractometer at specified temperature. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evolves volatile components by gentle heating, then weighs residual solids after drying to constant weight. |
| Odor | Sensory Evaluation | Assesses characteristic sulfone-like odor by trained personnel; deviation indicates degradation or contamination. |
