Setting up scanning functions 3-11
To set up a Voltage Scan function
1. In the MS method editor, click .
Alternative: Click Functions > Voltage Scan.
2. In the Voltage Scan function editor, enter the required parameters.
3. Click OK.
Start Time (min) The retention time (in minutes) at which the
function starts.
End Time (min) The retention time (in minutes) at which the
function stops.
Resolution The resolution, used to determine scanning
parameters.
Ionization Mode Specifies the ionization mode and polarity applied
during data acquisition.
FI Set up Opens the FI Set up dialog box, so you can specify
that an inter-scan current be applied to an field
ionization (FI) emitter.
Tip: This option is enabled only when you select FI+
or FI- as the Ionization Mode.
Data Specifies the type of data (centroid or continuum) to
be collected and stored on disk.
Scan Time (s) The duration of each scan, in seconds.
Inter-Scan Delay (s) The time between one scan’s end and the next scan’s
start, in seconds. No data are stored in this period.
