This manual contains procedures proposed in the literature for
microwave-assisted digestion of organic and inorganic samples. The
literature search was based on papers published in 2006 and 2007, because
previous years were covered in the first version of this manual .
Procedures employing microwave ovens designed for domestic use were
not included for safety reasons. On the other hand, digestion procedures
using flow-based systems were also not included because of the lack of
commercial equipments that would make them available for laboratories
performing routine analysis.
The compilation was focused on developed procedures using
commercial microwave ovens designed for laboratory applications. The
main focus was put on inorganic elemental analysis, but some extraction
procedures and procedures applicable for speciation analysis were also
included as important strategies that certainly will have a fast growing in
the coming years.
The compilation is not comprehensive, but reflects the experience of
the Group of Applied Instrumental Analysis (GAIA, Department of
Chemistry, Federal University of São Carlos, and Embrapa Cattle-
Southeast, São Carlos, SP, Brazil) and of the Group of Environmental
Analytical Chemistry (Department of Chemistry, Federal University of
Santa Maria, Santa Maria, RS, Brazil). However, it must be emphasized
that the listed procedures were not tested in the authors´ laboratories and
the authors cannot assume any responsibility about safety aspects.
ATTENTION: The experimental work with concentrated acids at high
pressures and temperatures is dangerous and may expose the analyst to
critical safety conditions.
The authors intend to follow this series of compilations about
microwave-assisted procedures with a publication
Preparation Information Newsletter, but the periodicity of this publication
and its publication either in paper or in a digital medium is still being
