Manufacturing Quality Control of Triisooctyl phosphite
| 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. |
| Acid Value | Acid-Base Titration with KOH ethanol solution | Measures free acidic impurities by titration with standardized potassium hydroxide solution in ethanol medium. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Compares sample color intensity against APHA platinum-cobalt standards or measures absorbance at specified wavelength. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Determines mass per unit volume based on resonant frequency shift of vibrating U-tube filled with sample. |
| Refractive Index at 20 C | Refractometry (Abbe refractometer) | Measures bending of light passing through sample to determine refractive index as function of composition and purity. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water via iodine generation and stoichiometric reaction with sample moisture. |
| Phosphorus Content | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Atomizes and excites sample; measures characteristic phosphorus emission line intensity for elemental quantification. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates chloride ions on anion-exchange column and detects them via electrical conductivity measurement. |
| Non-Volatile Residue | Gravimetric Analysis (Hot Plate Evaporation) | Evaporates known sample mass under controlled heating; weighs residual solids after solvent removal. |
| Flash Point | Closed Cup Pensky-Martens Tester | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized conditions. |
| Viscosity at 25 C | Rotational Viscometry (e.g., Brookfield) | Measures resistance to flow under defined shear rate and temperature using rotating spindle in sample. |
| Heavy Metals (as Pb) | AAS (Atomic Absorption Spectrometry) after acid digestion | Digests sample in nitric acid, then quantifies metal concentration by absorption of element-specific light wavelength. |
