Manufacturing Quality Control of Ethyl diphenylphosphinite
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Phosphorus Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies total phosphorus after acid digestion by measuring characteristic atomic emission lines. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES or ICP-MS | Measures trace metal concentrations following microwave-assisted acid digestion and plasma excitation/ionization. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection after ion exchange separation. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents or impurities by analyzing equilibrium vapor phase above heated sample. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral centers in solution at specified wavelength and temperature. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range over which solid transitions to liquid using controlled heating and visual observation. |
| Density | Digital Density Meter | Calculates density from oscillation period of U-tube filled with sample at controlled temperature. |
