Royal jelly from Apis mellifera is a highly active natural biological substance and is probably
one of the most interesting raw substances in natural product chemistry. Trace elements play …

This paper presents a portable, high-tech, low-cost, total reflection X-ray fluorescence
system. This system features a compact arrangement consisting of a 50 W X-ray mini-tube …

This is the seventeenth annual review published in JAAS of the application of atomic
spectroscopy to the chemical analysis of environmental samples. The review follows on …

Elements, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, and Sr in bee honey samples were
determined using an improved dry ashing (DA) method for XRF with Mo-secondary target …

This annual review of X-ray fluorescence covers developments over the period 2000–2001
in instrumentation and detectors, matrix correction and spectrum analysis software, X-ray …

Physical methods make it possible to combine analytical imaging with isotopic labelling in
biological studies. With radioactive isotopes, track-radioautography may be used (in parallel …

Human urinary stones, taken from recurrent urinary stone ailing patients, were investigated
with an energy dispersive x‐ray fluorescence (EDXRF) spectrometer. The concentrations of …

Micro X-ray fluorescence spectroscopy (micro-XRF) is one of the latest and very dynamic
branches of X-ray fluorescence spectroscopy. Here “micro” indicates that localised regions …

A simple new spectrophotometric method for the simultaneous determination of Cu, Fe and
Zn in honey using PLS-2 multivariate calibration method has been proposed. Pr was used …

The elemental concentrations of U, Th, Rb and K were measured in some honey samples of
different origins by ICP-mass spectrometry. The samples were collected from local markets …
