PRETREATMENT APPARATUS FOR ELEMENTAL ANALYSIS, AND ELEMENTAL ANALYZER

摘要: PROBLEM TO BE SOLVED: To provide a pretreatment device for elemental analysis preventing air from mixing, markedly reducing variation, and improving analytical capability in by an analyzer, even if trace amount of sample is used. SOLUTION: The 2 includes sample-holding member 11, valve 12 introduction, oxidation tube 13, reduction 14, reaction gas feed means 15, carrier 16, switching 17, which feeds switched to the chromatograph 3. apparatus moisture trap 18, removes (H2O) passes through 14. passing 18 separated 3 sent analyzer 5. 17 provided inside chamber 19. 19 introduces inert (He or Ar) as purge fed 22. Mixing can be intercepted. COPYRIGHT: (C)2011,JPO&INPIT
