DURIP - Acquisition of an Inductively-Coupled Plasma Mass Spectrometer with Laser Ablation Source for Surface Characterization

摘要

The instrument and projects listed in the brief have been properly installed and executed. The 820 ICP-MS is a universal 90 degree quadrupole mass spectrometer equipped with a collision reaction interface (CRI) front end. The CRI allows low interference which reduces common polyatomic interferences on As, Se, Cr, V and Fe, thus achieving lower detection limits in the plasma, especially for samples with complex matrices. The CRI increases sensitivity and lowers time to acquisition based of the principals that collision dissociation occurs prior to mass selection, eliminating the need for the CID optics in other ICP-MS. Laser Ablation for material characterization is produced from a New Wave (ESI) LS-213 Tempest Laser Ablation System. This is ideal for determining surface composition with ICP-MS. This instrument provided an excellent resource in our multiuser facility and the broad adoption of the ICP- MS technology in industry and academia meant that our students and postdocs can be trained in the most relevant analytical approaches for materials research.
