Manufacturing Quality Control of ETHANOL-D
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (C2H5OD content) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on volatility and retention time relative to certified reference standard. |
| Water content | Karl Fischer Titration | Volumetric or coulometric titration measuring water via stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residual Solvents (e.g., methanol, acetone) | Gas Chromatography (GC) with FID or MS | Separation and quantification of volatile impurities using capillary column and selective detection. |
| Acidity (as acetic acid) | Acid-Base Titration | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Non-volatile Residue | Gravimetric Analysis | Evaporation of sample under controlled conditions followed by weighing of residual solids after drying. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element detection via atomic emission from plasma-excited atoms in solution digest. |
| Chloride (Cl-) | Ion Chromatography (IC) | Anion separation on ion-exchange column with conductivity detection after elution with carbonate/bicarbonate buffer. |
| pH (10% v/v aqueous solution) | Potentiometric Measurement | Measurement of hydrogen ion activity using calibrated glass electrode and reference electrode. |
| UV Absorbance (220 nm, 235 nm, 280 nm) | UV-Vis Spectrophotometry | Quantification of organic impurities by absorbance at specified wavelengths relative to solvent blank. |
| Density at 20 degC | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 degC | Digital Refractometer | Measurement of light bending angle at air-sample interface to infer purity and concentration. |
| Peroxides | Colorimetric Assay (e.g., with KI/starch) | Oxidation of iodide to iodine by peroxides, forming blue starch-iodine complex measured spectrophotometrically. |
