The Nu Plasma II is a double focussing magnetic sector instrument, designed to provide the best possible precision for simultaneous isotope ion detection. The instrument utilises a unique, patented variable dispersion ion optical Zoom lens enabling the simultaneous measurement of the isotopes of elements from lithium to uranium on its static collector of sixteen Faraday detectors and up to six ion-counting electron multipliers.Ground potential analyser operation provides ease of access, serviceability and excellent reliability. With its high precision, accuracy, reliability, upgradability and flexibility, the Nu Plasma II represents a major advancement in Multi-Collector ICP technology, making it the instrument of choice for Geological/Earth Science, Environmental Science. Biochemistry, Biomedical Science and Nuclear Science laboratories.
