Manufacturing Quality Control of TRIS(NONYLPHENYL) PHOSPHITE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibrated standard using retention time matching and response factor correction. |
| Acid Value | Acid-Base Titration with KOH ethanol solution | Measures free acidic impurities by titration with standardized potassium hydroxide in ethanol medium using phenolphthalein indicator. |
| Hydrolyzable Chlorides | Potentiometric Titration with AgNO3 | Determines chloride ions released upon controlled hydrolysis by titration with silver nitrate using silver indicator electrode. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water via iodine generation and stoichiometric reaction with sample water in anhydrous methanol-based reagent. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness intensity by comparing sample absorbance at 455 nm to APHA platinum-cobalt standard scale. |
| Phosphorus Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures total phosphorus after acid digestion by detecting characteristic P emission line at 213.6 nm. |
| Heavy Metals (as Pb) | Atomic Absorption Spectrometry (AAS) after wet digestion | Quantifies lead and other heavy metals following microwave-assisted nitric-perchloric acid digestion and flame or graphite furnace AAS. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic ash content by weighing residue remaining after high-temperature (700-800 C) incineration. |
| Refractive Index | Refractometry at 20 C | Measures bending of light through liquid sample at specified temperature to assess purity and consistency of molecular composition. |
| Density | Oscillating U-tube Densitometry | Determines mass per unit volume via precise measurement of oscillation period of a filled U-shaped glass tube. |
| Non-Volatile Residue | Gravimetric Evaporation | Quantifies residue left after controlled evaporation of a known sample mass under nitrogen stream at 105 C. |
| Odor | Sensory Evaluation by Trained Panel | Assesses presence and intensity of off-odor against reference standard using standardized organoleptic protocol. |
