Trace Element Microanalysis in Iron Meteorites by Laser Ablation ICPMS.
A laser ablation microanalysis system has been developed that can analyze trace elements with a sensitivity in the ppb range, using a CETAC LSX-200 laser ablation system with a Finnigan Element. This capability has been applied to a set of iron meteorites to demonstrate the laser microprobe's analytical capability for the determination of platinum group elements (PGEs) with a spatial resolution...
متن کاملCapillary Electrophoresis as a New Tool in Forensic Toxicological Analysis
The basic aspects of capillary electrophoresis (CE) such as: instrumentation, separation modes and its chief domains of use in forensic analysis are presented. Micellar electrokinetic capillary chromatography (MECC), capillary zone electrophoresis (CZE) and chiral separations – the most often used separation modes in drugs analysis – are described. The main directions of development of CE metho...
متن کاملTrace samples of human blood in mosquitoes as a forensic investigation tool.
Investigations of any type of crime invariably starts at the crime scene by collecting evidence. Thus, the purpose of this research was to collect and analyze an entomological trace from an environment that is similar to those of indoor crime scenes. Hematophagous mosquitoes were collected from two residential units; saliva of volunteers that were residents in the units was also collected for g...
متن کاملA sensitive and quantitative element-tagged immunoassay with ICPMS detection.
We report a set of novel immunoassays in which proteins of interest can be detected using specific element-tagged antibodies. These immunoassays are directly coupled with an inductively coupled plasma mass spectrometer (ICPMS) to quantify the elemental (in this work, metal) component of the reacted tagged antibodies. It is demonstrated that these methods can detect levels of target proteins as ...
متن کاملTrace-element analysis in clinical chemistry.
Present knowledge of human bodily contents and concentrations in blood, urine, and hair of 11 essential trace elements and 17-22 nonessential inert or toxic trace elements is reviewed and summarized. Analyses of trace elements are applicable as diagnostic aids and indices for therapy in a number of clinical conditions. Techniques are not difficult, and analyses will probably become more or less...
