Microwave digestion for analysis of metals in soil

Communications in Soil Science and Plant Analysis, 1998
Abstract Microwave digestion using either only nitric acid or a mixture of nitric acid and hydrogen peroxide is an innovative technique used widely for elemental analysis of soil and plant samples. Only limited information, however, is available on comparisons of digestions with or without hydrogen peroxide.

Microwave digestion of fertilizers and soil amendments

Communications in Soil Science and Plant Analysis, 1996
Abstract The trace element pollution hazard of the continuous and large scale application of fertilizers and other amendments to soils depends in part on the chemical composition of these materials. Complete sample dissolution is generally required prior to total elemental analyses.

Microwave-Assisted Enzymatic Digestions

2009
Despite advances in “top-down” mass spectrometric methods for characterizing proteins, the traditional “bottom-up” approach of digesting a protein into smaller peptides followed by either peptide mass fingerprinting or reverse-phase separation and tandem mass spectrometric identification remains the most widely employed analytical method for protein ...

Microwave-Assisted Protein Digestion in a Plate Well for Facile Sampling and Rapid Digestion

Analytical Chemistry, 2017
Protein digestion is one of the most important processes in proteomic analysis. Here, we report microwave-assisted protein digestion in a plate well, which allows for facile sampling as well as rapid protein digestion based on the combination of highly stable enzyme immobilization and 3D printing technologies.

Microwave-Assisted Chemical Digestion of Proteins

2009
Chemical proteolysis is often employed as an alternative or complementary analytical tool to enzyme-mediated proteolysis for the characterization of proteins by mass spectrometry. Acids and other chemicals can be selected to cut at either specific amino acid residues or at chemically labile sites of a protein and may offer a harsher alternative ...

MICROWAVE AND ULTRASOUND DIGESTION OF COAL ASH

2012
Determination of trace elements in coal ash samples has always been an interesting area of environmental research. A good number of instrumental techniques, atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission spectrometry, X ray fluorescence, and neutron activation analysis have been proposed for multi-elemental analysis of
