Atomic mass spectrometry

Untitled

“…This information about the chemical makeup of the ultrastructure could be examined in light of the conventional nutritional parameters, for example rumen degradability, post-rumen degradability of nutrients, and used for prediction of nutritive value of feeds or accessibility of various enzymes for digestion of nutrients (Yu, 2004). 13C, 3H and 1H nuclear magnetic resonance, fast atom bombardment mass spectroscopy, and mass ionisation spectroscopy have been used for the analysis, characterization and structure elucidation of compounds in environmental, clinical and biological materials (Gamble et al, 1996;Bacon et al, 1999;Stobiecki and Makkar, 2004). These recent techniques have applications in nutritional, environmental, and toxicological investigations, especially in understanding complex pathways in biological systems.…”

The Effect of Plasma Reactions on Arsenic Measurement by ICP Spectrometry

“…Many techniques have been reported to control and suppress the spectral interferences such as the correction equation, the removal of interfering elements and/or compounds, low temperature plasma, and high resolution mass spectrometry. [11][12][13][14][15][16] Recently, the collision/reaction gas cell methods have been applied to ICP-MS to remove the interferences of coexisting ions. [17][18][19][20][21] Helium (He), H2, NH3, CH4, and O2 are usually used as collision/reaction gases in this technique and some interference are reduced based on the following physical/chemical phenomena such as the kinetic energy discrimination (KED), collision induced dissociation (CID), oxidization, etc.…”
