Method for the detection of organic compounds in titanium tetrachloride by large-volume headspace thermal desorption gas chromatography-mass spectrometry |
| abstract |
The invention discloses a large-volume headspace-thermal desorption-gas chromatography-mass spectrometry combined detection method for organic matter in titanium tetrachloride. The invention includes the following steps: hydrolyzing titanium tetrachloride, putting it into a large-volume headspace sampler for heating, and simultaneously adsorbing organic matter in the headspace gas with an adsorption tube; after sampling, putting the adsorption tube into a thermal analyzer for analysis, and analyzing The outgoing substances are introduced into the GC-MS for testing, and the GC-MS data is analyzed to determine the organic impurities in titanium tetrachloride. The invention has accurate qualitative and high sensitivity, and the detection limit can be as low as ng/kg level. Provide scientific and effective data for quality monitoring of titanium tetrachloride production and recycling, polyolefin catalyst research and development. |
