      Pyrolysis-Membrane Inlet Mass Spectrometry.

AB  - Eucommia ulmoides gum (EUG) is a natural polymer predominantly consisting of 
      trans-1,4-polyisoprene. Due to its excellent crystallization efficiency and 
      rubber-plastic duality, EUG finds applications in various fields, including 
      medical equipment, national defense, and civil industry. Here, we devised a 
      portable pyrolysis-membrane inlet mass spectrometry (PY-MIMS) approach to 
      rapidly, accurately, and quantitatively identify rubber content in Eucommia 
      ulmoides (EU). EUG is first introduced into the pyrolyzer and pyrolyzed into tiny 
      molecules, which are then dissolved and diffusively transported via the 
      polydimethylsiloxane (PDMS) membrane before entering the quadrupole mass 
      spectrometer for quantitative analysis. The results indicate that the limit of 
      detection (LOD) for EUG is 1.36 mug/mg, and the recovery rate ranges from 95.04% 
      to 104.96%. Compared to the result of pyrolysis-gas chromatography (PY-GC), the 
      average relative error is 1.153%, and the detection time was reduced to less than 
      5 min, demonstrating that the procedure was reliable, accurate, and efficient. 
      The method has the potential to be employed to precisely identify the rubber 
      content of natural rubber-producing plants such as Eucommia ulmoides, Taraxacum 
      kok-saghyz (TKS), Guayule, and Thorn lettuce.
