The use of micro-energy dispersive X-ray fluorescence spectrometry (μ-XRF) combined with a multivariate approach to determine element variation and distribution in tobacco seedlings exposed to arsenate
Here, we present a new scheme of analysis combining micro-energy dispersive X-ray fluorescence spectrometry (μ-XRF) with a multivariate approach that allows to establish the inter-correlation of multiple elements and their elemental map in plants. The main advantage of this procedure is that XRF spectral profiles can be analysed directly, by means of principal component analysis (PCA), allowing a quick interpretation of the results.
