Manufacturing Quality Control of Bis(methylthio)methane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by separation and flame ionization detection relative to internal/external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color | Visual Comparison or APHA Color Scale | Compares sample color against platinum-cobalt standard solutions under controlled lighting conditions. |
| 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 to infer purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates known volume at specified temperature and weighs non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame. |
| Sulfur Content | Combustion IC (Ion Chromatography) | Oxidizes organic sulfur to sulfate, then detects sulfate anion concentration via conductivity detection. |
| Non-Volatile Matter | Gravimetric Analysis | Dries sample at 105 C to constant weight and measures residual solids. |
| Odor Profile | Gas Chromatography-Olfactometry (GC-O) | Separates volatile components and assesses odor characteristics via human sensory panel. |
| Trace Aldehydes | Derivatization GC-MS | Converts aldehydes to stable oximes or hydrazones, followed by separation and mass-selective detection. |
