Microwave-assisted sample preparation in analytical chemistry
FE Smith, EA Arsenault - Talanta, 1996 - Elsevier
The speed and efficiency of instrumentation for chemical analysis has improved dramatically
over the past twenty years. Until recently, however, methods of sample preparation had not
changed to keep pace, so this had become the slowest step in analytical chemistry …

Applications of microwave digestion technique for elemental analyses
HM Kuss - Fresenius' journal of analytical chemistry, 1992 - Springer
The acceptance of microwave digestion technique is based on procedures successfully
carried out for most different kinds of samples. It is not only the knowledge of the
mechanisms how microwaves interact with the material scientists deal with but more the …

Elemental analysis of renal slices by proton-induced X-ray emission.
T Lowe, Q Chen, Q Fernando, R Keith… - Environmental health …, 1993 - ncbi.nlm.nih.gov
We optimized proton-induced X-ray emission (PIXE) for tissue analysis in a toxicity-
disposition study. We used cultured rabbit renal slices as the biological system to
demonstrate the use of PIXE analysis. The renal slices were exposed to HgCl2, CdCl2 …

Modified fast rejoining of chromosomes after fractionated X-ray exposures with iron and copper sulfate pretreatments related to uptake detected by PIXE analysis in …
KT El Araqi, J Gilot-Delhalle, I Roelandts… - … and experimental botany, 1997 - Elsevier
Nigella damascena dry seeds were irradiated with X-rays (250 kV) at fractionated exposures
(2× 40 and 2× 20 Gy) separated by time intervals ranging from 120 to 240 s. A decrease of
chromosome aberrations (threshold) observed with 60 Co γ-rays between 130 and 140 s …

EDXRF study of the effects of Cr on the growth of barley seedlings
Energy‐dispersive x‐ray fluorescence spectrometry was used to determine Cr and
bioessential trace elements (Fe, Zn, Cu, Mn) in the leaves and roots of barley seedlings. The
thin‐film approach, secondary target excitation and microwave acid digestion were applied …
