ICP-MS systems

Agilent 8800Agilent™ 8900 triple quadrupole inductively coupled plasma mass spectrometer (ICP-QQQ) and the Agilent™ 1260 LC system. 

This is our newest ICP-MS, it’s a great addition to our lab.  The ability to do reactive gas chemistry and mass shift analytes gives us great detection limits (around 1 ng/L) for tricky elements like Cd and As in urine.

This instrument was acquired in May 2016. It has excellent sensitivity; equivalent to the 8900. These instruments share the same basic lens and detector designs that allow for enhanced ion throughput. Often when using hyphenated techniques such as laser ablation of biological samples interference can be an issue, but either the 7900 ICP-MS or 8900 ICP-QQQ can be used to provide excellent multi-element detection in no-gas mode.

This instrument is the workhorse for routine trace element analysis at the TEA Core.  We run most biological sample digests with this instrument.  We have a CETAC Express system configured with the autosampler which speeds up sample analysis, eliminating the rinse time of conventional autosamplers.  We typically run no gas mode for both light and heavy elements (Be, B, Al, Hg, Pb, Tl, U), and in He mode for everything else (and Al again just to check). The exception to this is analysis of Cd and Se, which we typically run in hydrogen mode.
