User Interface - Global Parameters Pane

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 (LC/MS).

User Interface - Source Parameters

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 (LC/MS) and Run a sequence to optimize a parameter (LC/MS).

Gas Temperature (°C)

The temperature of the nitrogen drying gas. See Gas Temperature (LC/MS).

Gas Flow (L/min)

The flow rate in L/min of the nitrogen drying gas. See Gas Flow (LC/MS).

Nebulizer (psi)

Nebulizer sets the pressure of the nitrogen nebulizing gas. See Nebulizer (LC/MS).

Capillary Voltage (V) - Positive

The voltage to apply to the capillary when acquiring positive ions. See Capillary Voltage (LC/MS).

Capillary Voltage (V) - Negative

The voltage to apply to the capillary when acquiring negative ions. See Capillary Voltage (LC/MS).

Capillary Current (nA)

This is a read-only value. See Capillary Current (LC/MS).

Chamber Current (µA)

This is a read-only value. It shows the current in the spray chamber.
