Manufacturing Quality Control of 3-Ethylthiophene
| 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 calibrated column and detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent, measured by endpoint current change. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein or potentiometric endpoint detection. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass to dryness under controlled temperature, followed by weighing of non-volatile residue. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color against platinum-cobalt standard solutions using APHA scale; spectrophotometric method measures absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Measurement of sample density via oscillating U-tube principle, calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determination of refractive index using total internal reflection angle measurement with a calibrated Abbe refractometer. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion and matrix matching, based on absorption of characteristic wavelength light by ground-state atoms. |
| Sulfur Content | Combustion Ion Chromatography (CIC) | Oxidative combustion converts sulfur compounds to sulfate ions, which are separated and quantified by conductivity detection. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of sample under vacuum at specified temperature, followed by weighing of residual solids. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of volatile odor-causing impurities by retention time and mass spectral fragmentation patterns. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on an ion-exchange column and quantification via conductivity detection after eluent suppression. |
