Checking the Instrument Status of your Agilent Single Quadrupole LC/MS System Using OpenLab CDS

The (+) icon indicates that all the rows in the Acquisition Parameters table in the current method have a Positive polarity.
If the icon alternates between positive and negative, then the current method has at least one row with positive polarity and one row with negative polarity.

The (-) icon indicates that all the rows in the Acquisition Parameters table in the current method have a Negative polarity.
If the icon alternates between positive and negative, then the current method has at least one row with positive polarity and one row with negative polarity.

 The type of ion source is shown next to this icon, in this example is an ESI source running in positive mode. If the source is a multimode source (MMI), then the Ion mode (ESI, APCI, or ESI+APCI) is also shown.

This icon indicates that the LC stream is directed to the mass spectrometer.

This icon indicates that the LC stream is being directed to waste.

This icon indicates whether the Calibrant in on or off. If the icon is coloured, then the calibrant is turned on.

If the icon is unavailable, then the Calibrant is off

You can turn the Calibrant on or off by right-clicking in the SQ instrument status pane and then selecting the Calibrant command in the shortcut menu.

This command sets the Single Quadrupole in a ready state. It will be is ready to start a run. The Gas Flow, Nebulizer, and the temperatures are set to the setpoints in the current method. Voltages are applied to the Instrument.

Sets the MS to Standby state, where it is not ready to run while saving Nitrogen.

• Quad Temperature is set to 100 °C.
• Drying gas heater temperature is set to 300 °C.
• Nebulizer pressure is set to 20 psig.
• Drying gas flow is set to three Standard Litres/Minute (SLPM) nitrogen.
• "Stream" selector valve set to LC > Waste
• If an APCI source is installed, vaporizer gas temperature is set to 325 °C.
• If an APPI source is installed, you can turn the APPI lamp on or off.

Turns on, or off the calibrant flow to the MS.

Changes the direction of the LC stream to the mass spectrometer, or to waste.

When the calibrant is turned on, the LC stream is diverted to waste

Vents the MS to atmospheric pressure. A warning message will be given when this option is selected because it can take several hours to re-establish the proper vacuum levels and to re-equilibrate temperatures in the case of an unwanted Vent of the MS.

Pumps down the MS system to achieve high vacuum. When the pump down process finishes, the MS is in the Standby state. You can monitor the vacuum status in the SQ tab in the Instrument Status window and check Rough Vac and High Vac values.

Opens the Schedule Tune dialog box so that you can schedule an Autotune or Check tune on your instrument.

Note: This feature is only available on Agilent LC/MSD iQ instruments.

Opens the Maintenance dialog box so that you can enable or disable some of the Early Maintenance Feedback (EMF) counters.

Note: This feature is only available on Agilent LC/MSD iQ instruments.

Opens a dialog box to allow you to choose a tune file from a list of Autotune or Check tune files. You can then review that Autotune or Check tune report.
