Manufacturing Quality Control of Diethylphosphorodithioate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Determination | Gas Chromatography (GC) | Utilizes capillary column separation with FID detection for quantification. Main component purity is calculated using area normalization or external standard method. Suitable for high-sensitivity analysis of volatile organophosphorus compounds. |
| Moisture Content | Karl Fischer Titration | Based on the stoichiometric reaction between iodine and sulfur dioxide in a pyridine/methanol system with water, moisture content is determined via potentiometric or volumetric titration to measure trace water levels. |
| Density | Density Meter Method (Specific Gravity Bottle or Digital Density Meter) | Measures the mass-to-volume ratio of the sample at standard temperature (e.g., 20°C) using calibrated instruments such as a density meter or specific gravity bottle to calculate the density value. |
| Refractive Index | Abbe Refractometer Method | Determines the refractive index of the sample under specified temperature (typically 20°C) using optical refraction principles, serving as an auxiliary indicator for identification and quality consistency. |
| Appearance and Color | Visual Color Comparison Method | Observation of liquid color and clarity under natural light or standard lighting conditions, compared with standard color scales or blank solvents to assess compliance with quality requirements. |
| Acidity / Free Acid Content | Acid-Base Titration | Uses phenolphthalein or potentiometric endpoint indication to titrate free acids in the sample with standardized sodium hydroxide solution, evaluating product stability and level of by-products. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | After heating the sample, volatile solvents migrate into the headspace, which are then analyzed by GC-FID or GC-MS to quantify residual organic solvents (e.g., toluene, ethanol). |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determines concentrations of harmful heavy metals such as lead, arsenic, and mercury to ensure compliance with pharmacopeial or industrial safety standards. |
| Thermal Stability / Decomposition Products | Accelerated Thermal Aging + GC/MS Analysis | Sample is kept at elevated temperature for a set period; decomposition products are analyzed by GC/MS to evaluate storage and usage safety. |
| Sulfur Content / Phosphorus Content | Elemental Analyzer or Oxygen Flask Combustion-Titration Method | After combustion or chemical conversion, total sulfur or phosphorus content is determined by titration or instrumental methods to verify structural integrity and consistency with theoretical values. |
