Manufacturing Quality Control of 766-92-7
| 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 generated in situ reacts 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 after wet digestion by measuring absorbance of ground-state atoms at characteristic wavelength. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Complete oxidation of organic sulfur to sulfate, followed by anion exchange separation and conductivity detection. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface at specified temperature (20 C) to assess purity and concentration. |
| Specific Gravity | Pycnometry | Determination of density relative to water at 20/20 C using calibrated glass pycnometer. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluation of yellowness intensity by matching sample color to APHA platinum-cobalt standard scale. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of fixed volume under controlled conditions, followed by drying and weighing of residual material. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Detection and identification of volatile odor-active impurities via retention time and mass spectral library matching. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Quantification of chloride ions using conductivity detection after anion exchange separation or silver nitrate titration with silver indicator electrode. |
