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).

Vaporizer (°C)

The temperature of the vaporizer. This parameter is only available if you have an APCI, APPI, or MMI source. See Vaporizer (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).

Corona Current (µA)

See Corona Current (LC/MS).

Corona Voltage (V)

This is a read-only value. It shows the voltage for the corona.

Charging Voltage (V)

See Charging Voltage (LC/MS).

Chamber Current (µA)

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

Nozzle Voltage (V)

The voltage at the nozzle of the Agilent Jet Stream source. This variable is only available if your source is an Agilent Jet Stream.
