Manufacturing Quality Control of 775-12-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as HCl) | Acid-Base Titration | Neutralizes acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Atomizes sample and measures characteristic emission wavelengths of metal elements in plasma. |
| Iron Content | AAS (Atomic Absorption Spectroscopy) | Measures absorbance of ground-state iron atoms at 248.3 nm in acetylene-air flame. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at 20 degC using calibrated refractometer. |
| Density | Pycnometry | Calculates density from mass of known volume of sample at specified temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color intensity against platinum-cobalt standard scale using 450 nm absorbance. |
| Volatile Impurities | Headspace GC | Detects low-boiling contaminants by analyzing vapor phase above heated sample vial. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid treatment and high-temperature incineration. |
