X-ray emission spectrography in comparison with many analytical tools provides a
nondestructive means of determining elemental concentrations in plant materials with …

The relative intensity of the radiation is measured by a suitable electronic detector and must
be compared with the intensity given by samples of known composition run under the same …

Plants can be analysed for the elements sodium, magnesium, aluminium, silicon,
phosphorus, sulphur, chlorine, potassium and calcium by X‐ray fluorescent spectrometry …

This chapter focuses on wavelength‐dispersive spectrometry, because at this time it offers
better resolution at longer wavelengths (ie, with light elements), and frequently offers shorter …

Publisher Summary The electron microprobe analyzer is an exciting new analytical tool. Soil
scientists are now able to analyze nondestructively and in situ the chemical composition of …

Possibilities of X-ray emission spectrometry with a glass beads technique for quantitative
total analysis of major constituents in soil samples were explored. Preliminary experiments …

X‐ray spectrometry can be used to analyse plants for elements of atomic number greater
than 20 at concentrations as low as 1 ppm. The most accurate results are obtained by …

Method Samples of plant material are dried at 70 C. in a forced hot-air oven for 48 hours and
ground in a Wiley mill to pass a 20-mesh stainless steel sieve as previously reported (5) …

Elemental analysis by X‐ray fluorescence spectroscopy is based on the principle that
primary x‐rays from a target tube cause the elements present in the sample to emit …

X-ray fluorescence spectrometry (XRFS) is a technique for the determination of elemental
abundances in samples that are normally presented for analysis in solid form (liquids can be …
