Atomic absorption and fluorescence spectroscopy with a carbon-filament atom reservoir: Part II. use of the atom reservoir in atomic fluorescence spectroscopy

摘要: Abstract The design and operation of an improved carbon-filament atom reservoir is described. improvements incorporated are: a rigid metal base, system water cooling the electrode supports, introduction laminar gas flow through cell, electrical contact between filament its supports use calibrated micropipettes to apply sample. Optimum conditions for determination by atomic fluorescence number metals are described limits detection reported. latter generally appear be somewhat better than those obtained flame methods, but it absolute size amount determined which most significant. coefficient variation single with cell less 3%.
