Manufacturing Quality Control of isooctyl diphenyl phosphite
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibrated standard using retention time matching and response factor correction. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Measures free acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color intensity against platinum-cobalt standard solutions or measures absorbance at specified wavelength. |
| Water Content | Karl Fischer Coulometric Titration | Determines trace water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Phosphorus Content | UV-Vis Spectrophotometry after ammonium molybdate reduction | Measures phosphomolybdenum blue complex absorbance after oxidation and reduction of phosphorus to orthophosphate. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Quantifies elemental metal concentrations by atomization and ionization in plasma followed by mass or optical emission detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue remaining after controlled high-temperature ashing and weighing. |
| Refractive Index | Refractometry at 20 degrees C | Determines ratio of light velocity in air versus sample using calibrated refractometer under temperature-controlled conditions. |
| Density | Digital Density Meter at 20 degrees C | Measures mass per unit volume via oscillating U-tube principle with temperature compensation. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions based on anion exchange retention and suppressed conductivity measurement. |
| Non-Volatile Matter | Gravimetric Evaporation | Determines residue weight after solvent evaporation under controlled temperature and vacuum conditions. |
| Odor | Sensory Evaluation (Standardized Panel) | Assesses presence and intensity of off-odor using trained personnel following defined grading scale and reference standards. |
