Laser-ablation Icp-ms Analyses of Meteoritic Metal Grains

Introduction: Lunar impact-melt breccias contain metal grains from the meteorites that formed the breccias. Because the breccias contain clastic material that may derive from older breccias, metal grains from earlier impacts may be present, too. The large subset of moderately mafic (8– 12% FeO), KREEP-rich (“LKFM”) melt breccias is particularly important because (1) these are the melt breccias ...

Agilent 8800 Triple Quadrupole ICP-MS: Understanding oxygen reaction mode in ICP-MS/MS

The use of oxygen as a reaction gas for the removal of interferences in quadrupole ICP-MS is well established. However, prior to the development of the Agilent 8800 Triple Quadrupole ICP-MS (ICP-QQQ), the use of oxygen had been limited to determination of a small number of analytes in simple, well defined matrices. This is because oxygen can react with matrix components, analytes and polyatomic...

ICP-OES, ICP-MS and AAS Techniques Compared

This article will briefly describe these three techniques, and point out the important criteria by which to judge their applicability to your own analytical problems. Table 1 below shows a checklist of common analytical requirements and may help in the assessment of the techniques. For many people with an ICP-OES background, ICP-MS is a plasma with a mass spectrometer as a detector. Mass spectr...
