其实我觉得大家争论的焦点是在EPA3545方法，chief说只有dione和supelco符合标准，jzy0719说别的也可以，哪位英文好的帮忙把下面的给翻译一下： 4.1 Pressurized fluid extraction device 4.1.1 Dionex Accelerated Solvent Extractor or Supelco SFE-400 with appropriatelysized extraction cells. Currently, cells are available that will accommodate 10-g, 20-g and 30- g samples. Cells should be made of stainless steel or other material capable of withstanding the pressure requirements (2000+ psi) necessary for this procedure. 4.1.2 Other system designs may be employed, provided that adequate performance can be demonstrated for the analytes and matrices of interest.
