Wj. Przybylowicz et al., INVESTIGATION OF NI HYPERACCUMULATION BY TRUE ELEMENTAL IMAGING, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 104(1-4), 1995, pp. 176-181
The newly implemented Dynamic Analysis method for on-line elemental im
aging was used to study Ni hyperaccumulation in Senecio coronatus (Thu
nb.) Harv. Asteraceae, one of only nine Ni hyperaccumulating plants fo
und in the African continent. Elemental maps were obtained from sample
s with thicknesses varying from 0.4 to 5 mg/cm(2) by assuming cellulos
e (C6H10O5) as constant matrix composition for the whole scanned area.
The agreement between point analyses and results inferred from maps i
s good for small thickness variations within scanned regions. Maps of
very inhomogeneous samples require a more time-consuming approach of t
hickness corrections in every pixel.
