Agilent 7500ce Quadrupole ICP-MS

Agilent 7500ce and Cetac Autosampler


An Agilent 7500ce inductively-coupled plasma mass spectrometer (ICP-MS) was installed in the Department of Geological Sciences during the spring of 2006. The Agilent  is housed in the Department’s ICP Mass Spectrometry lab which is a HEPA-filtered, positive pressure clean laboratory. The Agilent 7500ce is a quadrupole ICP-MS with an Octopole Reaction System for interference reduction, and an electron multiplier detector that operates simultaneously in pulse counting and analog modes. A unique log amplifier circuit extends dynamic range to 9 orders of magnitude with a high-speed analog mode (minimum dwell time 100usec) designed specifically for transient signal analysis. The Agilent 7500 ICP-MS is used for the analysis of liquids such as groundwater and seawater, dissolved carbonates and digested rocks. Solid samples can be analyzed without dissolution using the Department’s New Wave UP193FX excimer laser ablation sample introduction system.
