Manufacturing Quality Control of TRIS(TRIMETHYLSILYL)PHOSPHITE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component based on retention time and peak area against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines free acidic impurities by titration with standardized sodium hydroxide in alcoholic medium. |
| Phosphorus Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies total phosphorus after acid digestion by measuring characteristic atomic emission lines. |
| Chloride Impurity | 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 550-600 C. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace heavy metals after microwave-assisted acid digestion using mass spectrometric detection. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Measures weight loss under controlled heating to assess thermal stability and volatile impurities. |
| Color | Visual Comparison or Spectrophotometric Measurement (APHA scale) | Evaluates color intensity by comparison to platinum-cobalt standards or absorbance at 430 nm. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at specified temperature using oscillating U-tube principle. |
| Refractive Index | Abbe Refractometer | Measures bending of light through sample at 20 C to infer purity and composition. |
| Organic Impurities (by GC-MS) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies structurally related organic impurities using retention time and mass spectral matching. |
