Troubleshooting the Ion Trap ◗ Loss of Sensitivity: Clean End caps and ring electrode ◗ High Mass Noise: Clean spacer rings and endcaps. ◗ Lack of sensitivity/resolution/mass stability: Lack of helium or Air leak Notes: Full scan target: -Set to 5X10e7 for best sensitivity in the positive ion mode. -For best mass stability results, set to 2X10e7. -Set (2-3) times less in the negative ion mode. A typical value of 1X10e7 should be used. Positive/Negative switching: -Xcalibur allows for separate tune files. Pos/Neg scan segments can be used. ZoomScan target: -Set to (1-3)X10e6 for compounds with multiple charge. -Singly charged compounds will exhibit a slightly higher target. -For calibration with Cal Mix, set to 1X10e7.
