Manufacturing Quality Control of TRIPROPYLPHOSPHINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies tripropylphosphine peak area relative to calibrated standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acidity (as H3PO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample and measuring absorbance of characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via silver nitrate titration using silver electrode for endpoint detection. |
| Phosphine Oxides (e.g., TPPO) | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies phosphine oxide impurities using reverse-phase column and UV detection. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample to determine purity and concentration based on Snell's law. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporates known volume at controlled temperature and weighs residual material. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies volatile odor-causing impurities by retention time and mass fragmentation patterns. |
