Microwave digestion of hardly dissoluble samples
Journal of Radioanalytical and Nuclear Chemistry, 2011This paper describes a method for digestion of hardly dissoluble samples such as soil, sand, glass fiber and cellulose filters via microwave. The evaluation of this method was conducted by automatic TDCR liquid scintilation counter Hidex 300 SL. The alpha tracer 244Cm was used for the assessment of efficiency.

Semimicro Determination of COD Employing Microwave Digestion
Environmental Engineering Science, 2003A modified semimicro method is described for determining chemical oxygen demand (COD) employing microwave (MW) digestion (0.5 min exposure at 1,000 W power, and 10 min exposure at 250 W power) with a titration assessment. Composition of reaction mixture was the same as that of the usual reflux method.

Microwave digestion for analysis of metals in soil
Communications in Soil Science and Plant Analysis, 1998Abstract 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, 1996Abstract 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.

Application of microwave digestion to the analysis of peat
The Analyst, 1987A microwave digestion technique for the dissolution of peat is described and compared with a dry ashing method and a nitric-perchloric-hydrofluoric acid wet digestion. Peat samples with different organic matter contents were used and Ca, Mg, Fe, Al, Na, K, Mn, Zn, Cu and Li were determined by atomic absorption spectrometry.

Microwave-Assisted Enzymatic Digestions
2009Despite 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, 2017Protein 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
2009Chemical 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 ...
