Manufacturing Quality Control of TRANS-1,2-DICHLOROETHYLENE
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Purity Analysis | Gas Chromatography (GC) | Capillary column separation is used with FID or ECD detectors for quantification. The purity of the main component is determined by peak area normalization or external standard method. Suitable for high-sensitivity, high-resolution measurements. |
| Impurity Content (e.g., cis-isomer, chlorinated hydrocarbons) | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines chromatographic separation with mass spectrometric identification, enabling accurate detection and quantification of trace impurities (e.g., cis-1,2-dichloroethylene, trichloroethylene), improving detection specificity. |
| Water Content | Karl Fischer Titration | Iodine reacts with sulfur dioxide in a methanol/pyridine system in the presence of water. Water content is determined by potentiometric or volumetric titration, with precision down to the ppm level. |
| Density | Density Meter Method (pycnometer or digital densitometer) | Measures the mass-to-volume ratio of the sample at a standard temperature (usually 20 °C) to calculate density, used to evaluate product consistency and as an indirect indicator of purity. |
| Color | Visual Color Comparison or Spectrophotometry | Sample color is compared with standard platinum-cobalt color solutions or measured by absorbance at a specific wavelength (e.g., 430 nm) to assess appearance quality and degree of oxidation or decomposition. |
| Acidity/Alkalinity | Acid-Base Titration | Using phenolphthalein or methyl orange as indicator, titrated with standard NaOH or HCl solution to detect acidic or alkaline impurities (e.g., residual HCl). |
| Volatile Residues | Headspace Gas Chromatography (HS-GC) | The sample is placed in a sealed headspace vial and heated to equilibrium. The vapor phase is then injected into a GC system for analysis, suitable for detecting low-boiling-point residual solvents or volatile impurities. |
| Heavy Metal Residues | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, ICP-MS is used to simultaneously detect multiple trace metal elements (e.g., Pb, As, Cd) with high sensitivity, ensuring compliance with industrial or environmental safety standards. |
