Each section in the SQ section of the Method Editor has two panes. The MS Global Parameters pane is the top pane in the Instrument Setup > SQ > Method section. It is visible when any of the Instrument Setup > SQ > Method sections are visible. See Advanced Acquire > MS Global Parameters Pane.
The actual values are shown in a read-only box next to the parameter.
When you run a sequence, you can override a source parameter. See Run a sequence and Run a sequence to optimize a parameter.
The temperature of the nitrogen drying gas. See Gas Temperature.
The flow rate in L/min of the nitrogen drying gas. See Gas Flow.
Nebulizer sets the pressure of the nitrogen nebulizing gas. See Nebulizer.
The voltage to apply to the capillary when acquiring positive ions. See Capillary Voltage.
The voltage to apply to the capillary when acquiring negative ions. See Capillary Voltage.
This is a read-only value. See Capillary Current.
This is a read-only value. It shows the current in the spray chamber.
When a new method is created or if the ion source is changed, the ion source settings are set to the default values shown below.
