The ICAP quad ICP-MS from Thermo is a mature instrument that follows the highly succesful XSeries mass spec and is characterized by a uniquely stable signal and the incredible range of concentrations that can be measured simultaneously with really high precision due to the fast scanning ability of the machine. The ICAp is also among the most commonly used instruments in U-Pb geochronology surpassing many other quadrupole and even some of the older high resolution magneitc secgtor instruments in precision and accuracy.
The newest addition to the family of 193 nm Exicmer lasers is Iridia from Teledyne. It is a next generation instrument with a highly potent set of software packages that allow data manipulation including geochronology data reduction. Chemical mapping and reduced spot sizes for laser ablation measurements are among the new tools that open up new possibilities in geochemistry and geochronology.
We have a Cetac autosampler for liquid sample introduction. We have a variety of nebulizers and accessories for sample introduction that give our facility a certain flexibility in terms of the type of sample introduced in the mass spectrometer.
This new instrument purchased in 2024 provides a complementary tool to measure major and some routine trace elements in rocks and rock forming minerals. materials are being fused with lithium tetraborate flux in the prep lab and measured on the multi turret instrument, which is pretty well standardized against some of the most common standards used in major elemental silicate geochemistry globally.
We are equipped with mini columns for small scale chemistry work done in collaboration with the Chemistry Department of the University of Bucharest. Some samples such as carbonates can be dissolved in clean lab mode to be introduced in the ICP-MS in solution mode.
