background: due to the evacuation of some industrial wastewaters to arvandrood, the presence of the radionuclide material in the river is likely. the purpose of this study was to determine the radioactivity rate in arvandrood land area to the persian gulf. methods: : the concentration of cesium radionuclide (cs137) was measured in 20 sediment samples and 8 water samples which were collected fro...

Elucidation and Improvement of Algorithms for Mass Spectrometry Isotope Trace Detection Rob Smith Department of Computer Science, BYU Doctor of Philosophy Mass spectrometry facilitates cutting edge advancements in many fields. Although instrumentation has advanced dramatically in the last 100 years, data processing algorithms have not kept pace. Without sensitive and accurate signal segmentatio...

Controls in food industry are fundamental to protect the consumer health. For products of high quality, warranty of origin and identity is required and analytical control is very important to prevent frauds. In this article, the "state of art" of mass spectrometry in enological chemistry as a consumer safety contribute is reported. Gas chromatography-mass spectrometry (GC/MS) and liquid-chromat...

Mass Spectrometry The ionization of N-protonated Verapamil by electrospray (ESI) is investigated in the Communication (e202116794) W. Scott Hopkins et al. using differential mobility spectrometry (DMS). spectral behaviour caused protonation-induced chirality.
