The Agilent 7700x is bundled with a collision/reaction cell in helium mode that offers higher sensitivity, lower backgrounds, and more effective polyatomic interference removal in complex sample matrices. The 7700x also includes a frequency-matching RF generator. Our instrument, installed in 2010, is equipped with an ASX-500 autosampler.
At PCIGR, the Agilent 7700x is used for the trace element analysis of a wide range of materials, including rocks, minerals, water, organic matter (e.g., digested bee and fish tissue (Li et al., 2020), culture media, and other organic matter such as digested honey (Smith et al., 2019) and filters), and column calibration (for ion chromatography in preparation for isotope analysis).
Recent applications include determining heavy metal concentrations in water analyses from water purification projects and water treatment plants, and leaching studies in Materials Science and Engineering.
At PCIGR, the Agilent ICP-MS can also be connected to the Excimer Laser Ablation System RESOlution M-50-LR.
