After you complete the instrument configuration, use the Thermo Tune Plus application to
configure the NSI source parameters. For additional information, refer to the Tune Plus Help.
To set the NSI source parameters
1. Open the Tune Plus application by choosing
Start > All Apps

in the Spray Voltage (kV) box
).
Use 1.90 kV as the start value for the spray voltage. If the intensity of the full-scan
spectrum is low, gradually increase the spray voltage to improve the spectrum. The
recommended range for the spray voltage is 1.40–2.40 kV.
