Elemental Analysis Of Biological Matrices By Laser Ablation High Resolution Inductively Coupled Plasma Mass Spectrometry (La-Hr-Icp-Ms) And High Resolution Inductively Coupled Plasma Mass Spectrometry (Hr-Icp-Ms), Waleska Castro
FIU Electronic Theses and Dissertations
The need for elemental analysis of biological matrices such as bone, teeth, and plant matter for sourcing purposes has emerged within the forensic and geochemical laboratories. Trace elemental analyses for the comparison of aterials such as glass by inductively coupled plasma mass spectrometry (ICP-MS) and laser ablation ICP-MS has been shown to offer a high degree of discrimination between different manufacturing sources. Unit resolution ICP-MS instruments may suffer from some polyatomic interferences including 40Ar16O+, 40Ar16O1H+, and 40Ca16O+ that affect iron measurement at trace levels. Iron is an important element in the analysis of glass and also of interest for the …
