Manufacturing Quality Control of TRIBUTYLPROPYNYLSTANNANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component based on peak area relative to calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomic absorption of characteristic wavelengths after acid digestion. |
| Tin Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures total tin concentration via emission intensity of tin-specific spectral lines. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Determines mass loss under controlled heating to assess thermal stability and volatile content. |
| 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 | Measures mass per unit volume using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Identifies and quantifies volatile organic solvents by headspace gas analysis. |
