Manufacturing Quality Control of 2929-52-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component using retention time and peak area against calibrated standard. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies low-boiling organic impurities based on mass spectral fragmentation patterns. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration | Determines free acidic species by titration with standardized KOH solution using phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing at 500-600 C. |
| Heavy Metals (Pb, Cd, Hg, Cr) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Detects trace metals by measuring element-specific atomic emission lines after plasma atomization. |
| Iron (Fe) Content | Atomic Absorption Spectroscopy (AAS) | Quantifies iron by measuring absorption of light at characteristic wavelength after atomization in flame. |
| Density | Pycnometry | Determines mass per unit volume using calibrated glass pycnometer at specified temperature. |
| Refractive Index | Refractometry | Measures bending of light through sample at 20 C using calibrated refractometer. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA Method | Evaluates yellowness by comparing sample color to platinum-cobalt standard solutions. |
| Viscosity | Capillary Viscometry | Measures flow time through calibrated capillary tube under gravity to calculate kinematic viscosity. |
