Manufacturing Quality Control of DIMETHYL PHOSPHOROCHLORIDATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (O,O-Dimethyl Phosphorochloridate) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on volatility and thermal conductivity differences; calibrated against certified reference standard. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl or phosphoric acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Electrochemical determination of water via iodine-sulfur dioxide reaction in methanol-based reagent; coulometric or volumetric mode. |
| Color (APHA) | Visual Comparison or Spectrophotometry (455 nm) | Measurement of yellowness intensity by comparing sample absorbance at 455 nm to platinum-cobalt standard solutions. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determination of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Measurement of light bending angle at air-sample interface to infer purity and composition via Snell's law. |
| Residue on Ignition | Gravimetric Analysis | Weighing non-volatile residue after controlled high-temperature ashing of a known sample mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of trace metal contaminants by measuring absorption of element-specific hollow cathode lamp radiation. |
| Chloride Impurities (as Cl-) | Potentiometric Titration with AgNO3 | Titration using silver nitrate and silver/silver chloride electrode to detect endpoint via potential change. |
| Phosphoric Acid Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anionic species (e.g., H2PO4-, HPO42-) on ion-exchange column followed by suppressed conductivity measurement. |
| Volatile Organic Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of low-boiling impurities (e.g., methanol, chloromethane) via retention time and mass spectral matching. |
| Appearance | Visual Inspection | Assessment of clarity and presence of suspended particles or phase separation under controlled white light against black/white background. |
