A pressure regulator is connected to the extraction cell outlet to the pressure regulator. The pressure regulator blocks fluid flow when the pressure at the pressure regulator inlet is below a predetermined pressure and permits fluid flow when above said predetermined pressure. The apparatus is free of operative association with a mechanical pump or with a compressed gas source other than the compressed gas source. An extraction method for using the above apparatus is described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pump-less method and apparatus for solvent extraction from a sample","description":"Apparatus for extracting organic analytes from a sample comprising a first compressed gas source connected to valving and a sample extraction cell connected to the valving.
