Manufacturing Quality Control of 70851-51-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibrated standard; uses non-polar capillary column. |
| Moisture Content | Karl Fischer Titration | Measures water via coulometric or volumetric iodine-based redox reaction. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution. |
| Density at 25 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA | Compares sample color intensity against platinum-cobalt standard scale. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride anions using conductivity detection after ion exchange. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption of element-specific wavelength. |
| Viscosity at 25 C | Rotational Viscometry | Measures resistance to flow under controlled shear rate using spindle rotation. |
| pH of 10% Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in aqueous dilution. |
| Volatile Organic Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identifies and quantifies low-boiling impurities via thermal desorption and mass spectral detection. |
