NAME OF THE INSTRUMENT
iCAP™ TQ ICP-MS spectrometer (Thermo-Fisher Scientific) coupled to NWR213 laser ablation system (Elemental Scientific Lasers-ESI)
GENERAL DESCRIPTION
Triple Quadrupole (TQ) Inductively Coupled Plasma Mass Spectrometer interfaced with Laser Ablation System (LA-ICP-MS) for the analysis of metallic and non-metallic inorganic materials in solid and solution samples.
The Laser Ablation System is also enabled to perform high resolution chemical imaging.
