User Interface

Tune file

The name of the current tune file. You can use the icons in the Tune Toolbar to open and save a tune file.

Fast scan

Whether or not the current tune file is a Fast scan tune file.

Ion source

The source that is configured with the current instrument.

Diverter

Whether the stream from the LC is going into Waste or into the MS.

Calibrant on

Whether or not the calibrant is flowing.

Polarity

Positive or Negative.

Scan type

Scan, SIM, or Profile.

Optics Parameters

Fragmentor (V)

The Fragmentor parameter controls the voltage applied to the exit of the capillary. The Fragmentor voltage affects the transmission and fragmentation of sample ions. See Fragmentor (LC/MS).

Skimmer (V) (on 6125, 6130, or 6135) or Skimmer 2 (V) (on 6120)

Skimmer control the voltage applied to skimmer 1. See Skimmer (LC/MS).

Octopole DC (V)

The Octopole DC controls the DC offset voltage applied to the octopole. See Octopole DC (LC/MS).

Octopole RF (V)

See Octopole RF (LC/MS).

Lens1 DC (V)

The voltage applied to Lens1. See Lens1 DC (LC/MS).

Lens2 DC (V)

The voltage applied to Lens2. See Lens2 DC (LC/MS).

Lens2 DC RF Off (V) (6125, 6130, and 6135)

The voltage applied to Lens2. See Lens2 DC RF Off (LC/MS).

Lens2 RF Enabled (6125, 6130, and 6135)

Whether or not the RF voltage on lens 2 is enabled. If you clear this check box, then the RF is off. This parameter is used on 6130 LC/MS model.

Lens2 RF (V) (6125, 6130, and 6135)

Lens2 RF sets the amplitude of the RF voltage. See Lens2 RF (LC/MS)

Lens2 RF Phase (°) (6125, 6130, and 6135)

See Lens2 RF Phase (LC/MS).

Ramp Parameters

See Ramp Section (LC/MS).
