Quadrupole ICP-MS

Agilent 7700x

The Agilent 7700 Series quadrupole ICP-MS is the successor to the company’s successful ICP-MS instruments, the 4500 Series and the 7500 Series. The Agilent 7700 is bundled with more advanced features: the instrument incorporates a 3rd-generation collision/reaction cell in helium mode that offers higher sensitivity, lower backgrounds and more effective polyatomic interference removal in complex sample matrices. The 7700 Series features other hardware developments, including a frequency-matching RF generator, as well as the Mass Hunter software. Our instrument is equipped with an autosampler (ASX-500 series).

At PCIGR, the instrument is used extensively for the trace element analysis of a wide range of materials including rocks, minerals, water, organic matter (e.g., animal tissue and culture media), and column calibration (for elemental separation in the clean labs). Applications include heavy metal concentrations in UBC drinking water and in honeys from Vancouver and surrounding areas, trace element characterization of USGS reference materials (basalt, andesite, rhyolite, granite, syenite), water samples from consulting companies, and reagent testing from the industry.

The Agilent ICP-MS was delivered to PCIGR in late 2010 and then relocated to the newly built nUBC laboratories in September 2011. After passing the testing stage in early 2011, the instrument has had users from EOAS; other departments at UBC such as Chemistry, Pathology, Soil Science, Chemical and Biological Engineering; Vancouver Island University; and Simon Fraser University.

The Agilent ICP-MS can also be connected to a laser ablation system. At PCIGR we have the possibility to connect the Agilent ICP-MS to the Excimer Laser Ablation System RESOlution M-50LR.
