Inductively Coupled Plasma Mass Spectrometry (ICPMS) Facility
Inductively coupled plasma mass spectrometry combines the efficient ionization of a high-temperature argon plasma to the rapid scanning, high sensitivity and good resolution capabilities of a quadruple mass spectrometer. The technique can produce high quality concentration data for a large number of elements using an appropriate range of sample weights.
Isotope ratios can be measured by ICPMS with sufficient precision for certain applications such as environmental lead source tracing. Isotope dilution may be used to determine concentrations of "difficult" or low-abundance elements.
We have two ICPMS instruments in operation: a HP 4500plus and a PerkinElmer ELAN DRCII. The latter is currently being set up for potential use of reaction gases (e.g., NH3,He, etc.) to eliminate Ar, matrix, and solvent-based spectral interferences. The ICPMS is used for chemical analyses of natural waters and acid digests of rocks, minerals, ores, sediments, soils and biota and laser ablated materials.
The ICPMS lab has a well supported infrastructure including a number of clean rooms, acid distillation, rock crushing/mineral separation and computer facilities. The University provided technical personnel with expertise in electronics, vacuum systems and machining.
Memorial's ICPMS lab is used by faculty and students throughout the University. Commercial work is accepted from external clients throughout the world. For solution-ICPMS we offer a set of analytical packages that are carried out on a routine basis, with submitted samples handled by appropriate technical staff on a straightforward cost-for-service basis.
