ray fluorescence spectrometry has been developed. The method is accurate and precise …

THE speed and versatility of X-ray fluorescence spectrometry is well established,'and many
papers have been published describing the application of this technique to the elemental …

The use of X-ray fluorescence spectrometryfor the analysis of plant tissue is well
established. First introduced in 1958 by Brandt and Lazar (2) for the determination of …

An energy dispersive X-ray fluorescence spectrometer for trace element analysis has been
constructed. The system consists of an Ag anode X-ray tube, a bent LiF crystal …

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) …

A method is presented for the determination of trace elements in plant materials. The
samples were composed of organic material, which was eliminated by wet ashing, large …

A numerical matrixcorrection technique is used to linearize fluorescent X-ray intensities from
plant material to permit quantitation of the measurable trace elements. Percentage …

Trace element concentrations in the range more than 10 μg/g in biological samples (milk
powder, potato powder, maize, plant ash etc.) were determined by energy-dispersive X-ray …

The basic problem of applicability of a x-ray fluorescent method for Ihe analysis of
agricultural products consists in rather low sensitivity of the majority of available instruments …
