Graphite analysis etv-icp-oes
WebTraditionally, most elemental analysis has been performed by either atomic absorption (AA) or optical emission spectroscopy (OES). Generally, the ultratrace (sub-ppb) elements were measured by graphite furnace atomic absorption (GFAA), a highly sensitive single-element technique. The trace and minor (ppb to ppm) elements were measured WebNov 15, 2013 · Mit dem Verfahren der ETV-ICP OES werden deutlich bessere Nachweisgrenzen im Vergleich zur Lösungsanalyse erreicht [5], außerdem erfolgt keine Beeinflussung der Spektrallinien durch OH-Banden (vom Wasser). Der Kalibrierung ist bei diesem Verfahren aber erfahrungsgemäß eine sehr große Aufmerksamkeit zu schenken [6].
