Manufacturing Quality Control of 7778-83-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution. |
| Refractive Index | Refractometry | Measures bending of light through sample at specified temperature to assess purity and composition. |
| Specific Gravity | Pycnometry or Digital Density Meter | Compares density of sample to water at standard temperature using calibrated volume or oscillating U-tube principle. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA | Evaluates yellowness by matching sample color to platinum-cobalt standard scale. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities remaining after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Identifies and quantifies volatile organic solvents using equilibrium vapor phase analysis. |
| Odor | Sensory Evaluation | Assesses conformity to characteristic floral, fruity odor by trained personnel under controlled conditions. |
| Appearance | Visual Inspection | Evaluates physical state (clear liquid), presence of particulates, cloudiness, or phase separation. |
| Boiling Range | Distillation (ASTM D1078) | Determines temperature interval over which 5% to 95% of sample distills under reduced pressure. |
