Manufacturing Quality Control of Di-tert-butylphosphine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separates and quantifies volatile solvents based on partitioning into headspace gas phase. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Phosphine Oxide Impurity | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies oxidation by-product using mass spectral fragmentation patterns and retention time. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Measures trace metal concentrations after acid digestion by detecting element-specific atomic emission lines. |
| Chloride Ion | Ion Chromatography (IC) | Separates and quantifies chloride anions using ion-exchange column and conductivity detection. |
| Non-Volatile Residue | Gravimetric Analysis | Determines residue after controlled evaporation and drying by measuring mass difference of evaporating dish. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Evaluates yellowness/browning intensity by matching to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement of total internal reflection. |
| Odor | Sensory Evaluation | Assesses characteristic pungent odor qualitatively by trained personnel under controlled conditions. |
