Manufacturing Quality Control of Methylthioethane
| 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 where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of sample under controlled conditions followed by weighing of non-volatile residue. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Comparison of sample color to APHA platinum-cobalt standards or measurement of absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Measures oscillation frequency of a U-tube filled with sample; correlates to mass per unit volume. |
| Refractive Index at 20 C | Refractometry | Determines bending of light passing through sample; related to molecular polarizability and concentration. |
| Boiling Range | Distillation (ASTM D86 or equivalent) | Measures temperature interval over which 10–90% of sample distills under controlled atmospheric pressure. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Sample combusted to convert sulfur to sulfate, then quantified via suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of sample in flame or graphite furnace; quantification via absorption of element-specific wavelength. |
| Non-Volatile Matter | Gravimetric Analysis after Solvent Evaporation | Dissolution in volatile solvent, filtration, evaporation, and weighing of insoluble residue. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation followed by electron ionization and mass spectral identification of trace volatile impurities. |
