Manufacturing Quality Control of 143487-47-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area against calibrated standard curve. |
| Moisture Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction with iodine and sulfur dioxide. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Evaluates color intensity by comparison to platinum-cobalt standards or absorbance at 455 nm. |
| Density | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through sample at specified temperature to assess purity and composition. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling contaminants by analyzing vapor phase above heated sample. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Quantifies trace metal elements after acid digestion using plasma excitation and optical emission detection. |
| Hydrolyzable Alkoxy Groups | Acid-Catalyzed Hydrolysis followed by GC | Determines methoxy group content via quantitative release of methanol after controlled hydrolysis. |
| Viscosity | Rotational Viscometry | Measures resistance to flow under shear stress using calibrated spindle and rotational speed. |
