achieves_planned_objective separation into different composition objective extraction Philippe Rocca-Serra extraction Person:Bjoern Peters nucleic acid extraction using phenol chloroform A material separation in which a desired component of an input material is separated from the remainder Current the output of material processing defined as the molecular entity, main component in the output material entity, rather than the material entity that have grain molecular entity. 'nucleic acid extract' is the output of 'nucleic acid extraction' and has grain 'nucleic acid'. However, the output of 'nucleic acid extraction' is 'nucleic acid' rather than 'nucleic acid extract'. We are aware of this issue and will work it out in the future. material component separation metadata incomplete
