Concentration Analyses via Inductively Coupled Plasma Mass Spectrometer

excell The ExCell is a quadropole ICPMS which is our work horse machine. It is can be used in conjuction with the UP193FX laser providing a much quicker near simultaneous elemental analysis of a sample which is crucial in laser ablation.

The ExCell was installed in October 2008, under the direction of Dr. Terry Plank. It is an ICP-quadrupole mass spectrometer, which includes an off-axis lens system which has decreased instrument backgrounds to < 0.5 cps. This ultra-sensitive ICP-MS is primarily dedicated to high precision trace element analyses of volcanic rocks and marine sediments, both as solid samples by laser ablation and by conventional dissolution. Routine precision in solution is 1-2% RSD for most trace elements.

 

attom The Attom is a magnetic sector high resolution ICPMS. It is used for analyses that require higher resolution to separate out peaks. It is also equipped with a faraday cup allowing a sensitivity range of up to 10^12 cps. The Attom can be used in conjuction with the UP193FX laser allowing us to measure in both laser and solution mode.

The Attom was installed in November 2009, under the direction of Dr. Terry Plank. It is high resolution magnetic sector ICPMS. This ultra-sensitive ICP-MS is primarily dedicated to samples needing higher resolving powers and isotopic ratios that are too low concentrations for the faraday cups on the MC-ICPMS. Routine precision in solution is 1-2% RSD for most trace elements.

The PQ2 has been a fixture at Lamont since the mid 1990's. It was decomissioned in 2009 to make way for a Nu Attom.
