Manufacturing Quality Control of Methyl propyl disulfide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; separation based on volatility and polarity. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in methanol/pyridine medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions using APHA scale at 455 nm. |
| Density at 20°C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20°C | Refractometry | Measures bending of light through liquid sample using Abbe refractometer calibrated with distilled water. |
| Sulfur Content | Combustion IC Analysis | Oxidizes sample to SO2, then detects sulfur by conductivity or UV fluorescence after absorption. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal ions after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelength. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporates specified sample volume to dryness and weighs residual solids after drying at 105 C. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies volatile odor-active impurities via retention time and mass spectral matching. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection after aqueous extraction. |
