Manufacturing Quality Control of METHYL BENZENESULFINATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water in the sample. |
| 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 | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by atomization in flame or graphite furnace and measurement of absorbance at characteristic wavelength. |
| Chloride Impurities | Ion Chromatography (IC) | Separation and quantification of chloride ions on an anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurities | Barium Sulfate Gravimetric Method | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, drying, and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color intensity against platinum-cobalt standard solutions at 455 nm using calibrated spectrophotometer. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle with temperature-controlled sample cell. |
| Refractive Index at 20 C | Abbe Refractometer | Determination of refractive index based on critical angle measurement of light passing through liquid sample. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of fixed volume under controlled conditions, followed by drying and weighing of residual material. |
| Organic Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Extraction of volatile components into headspace, separation by GC, and identification/quantification via MS detection. |
