Manufacturing Quality Control of 28460-01-7
| 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. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-pyridine medium. |
| Acidity (as H3PO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace metals by ionization in plasma and mass-selective detection with isotopic resolution. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column and conductivity detection. |
| Phosphoric Acid Esters (e.g., diethyl phosphate) | GC-MS | Identifies and quantifies related phosphoric ester impurities based on retention time and mass fragmentation patterns. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measures yellowness by comparing sample color to APHA platinum-cobalt standards at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Measures light bending angle through sample to infer purity and composition. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Quantifies weight loss under controlled heating to assess low-boiling or volatile impurities. |
| Sulfur Content | Combustion IC (Ion Chromatography after Combustion) | Oxidizes organic sulfur to sulfate, followed by anion-exchange separation and conductivity detection. |
