Agilent Technologies Agilent 7700 Series ICP-MS User Manual

G7200-90210 (Rev. A) MassHunter Workstation Quick Start Guide 11
Reference: For 7700s
The recommended tuning parameter values for 7700s are shown below.
*1 Generally, set the QP Bias at least 2 to 3V higher than OctP Bias.
*2 High-Energy Collision mode allows for enhanced reduction of interference under the Helium mode.
However, as it will also result in reduced low-mass sensitivity, it should be used in accordance with
the purpose of the analysis.
