Manufacturing Quality Control of TRI-N-BUTYLPHOSPHINE OXIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| 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. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature to infer purity and composition. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heats sample to 800 C and measures non-volatile inorganic residue as percent of original weight. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorption of characteristic atomic vapor line. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions via precipitation titration using silver nitrate and silver electrode endpoint detection. |
| Phosphorus Content | UV-Vis Spectrophotometry after Ammonium Molybdate Reaction | Measures phosphomolybdate complex absorbance at ~820 nm following oxidative digestion and color development. |
| Non-Volatile Residue | Gravimetric Evaporation | Evaporates known volume at 105 C and weighs residual material to assess suspended or high-boiling impurities. |
| Gas Impurities (O2, N2, CO2) | Gas Chromatography with TCD detector | Separates and quantifies low-molecular-weight gases using thermal conductivity detection and calibrated standards. |
