Manufacturing Quality Control of N-BUTYL ETHYL SULFIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies N-butyl ethyl sulfide peak area relative to internal/external standard using retention time and calibration curve. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acidity (as H2SO4) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Refractometry | Measures bending of light through sample at specified temperature using calibrated Abbe refractometer. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates fixed volume under controlled conditions and weighs non-volatile residue after drying. |
| Sulfur Content | Combustion IC | Oxidizes sample to SO2, then detects sulfur by UV fluorescence or conductivity after absorption in H2O2 solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring atomic absorption of ground-state atoms in flame or graphite furnace. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporates sample to dryness at 105 degC and weighs residual solids after cooling in desiccator. |
| Odor | Sensory Evaluation | Assesses presence and intensity of characteristic odor by trained personnel against defined reference standards. |
