Application Note: NEPTUNE and NEPTUNE Plus: Breakthrough in Sensitivity using a Large Interface Pump and New Sample Cone
11 January 2016

This application note reports the sensitivity enhancements and total ionization efficiency that can be achieved with the NEPTUNE Plus’ new features. The Thermo Scientific NEPTUNE Plus is a major update of the proven NEPTUNE MC-ICPMS platform. Among the new features is an improved pumping capacity option at the interface and a new sample cone to significantly enhance sensitivity, in particular for dry plasmas. Further enhancements to sensitivity arising from a new sample cone, “Jet sample cone”, are reported and the use of the large interface pump on the NEPTUNE Plus significantly increases sensitivity across the entire mass range.
