Graphite furnace atomic absorption spectrometry with nitric acid deproteinization for determination of manganese in human plasma. Kunnath S. Subramanian
A first cause of C contamination in both cases is the CO vapour pressure generated from graphite parts of the furnace hot zone. The CO pressures respectively measured during experimental runs with the two types of crucibles are shown on Fig. 8. During the melting stage at high temperature, this pressure is found lower with a SiCgraphite ...
A new sensitive method for antimony III determination by graphite furnace atomic absorption spectrometry GFAAS has been developed by using NbenzoylNphenylhydroxylamine BPHA and 1butyl3methylimidazolium hexafluorophosphate C 4 mimPF 6 single drop microextraction.
