Quadrupole Power Supplies

150-QC QUADRUPOLE POWER SUPPLIES SELECTION CHART
Mass Range, Sensitivity, Abundance Sensitivity, and Resolution are determined by the quadrupole rod size and the RF operating frequency. Increasing quadrupole rod size or operating frequency increases the Sensitivity, Abundance Sensitivity, Resolution, and High Energy Ion Transmission and Filtering. Decreasing the quadrupole rod size or the RF operating frequency increases the mass range. Application Notes on Quadrupole Power Supply operation are available in the Apps Note section. For more information ask for Product  Note RP_2201, "RF/DC and RF-only Power Supplies for Quadrupoles, Hexapoles and Octupoles".
