Where can I read the vacuum gauge pressure for a SCIEX mass spectrometer in Analyst® software?

For research use only. Not for use in diagnostic procedures.

Answer

The vacuum gauge pressure is usually at about 0.5 x 10e-5 for the mass spectrometer when it is idle, and 1.8–2.7 x 10e-5 when the collisionally activated dissociation (CAD) gas is on. For SCIEX legacy instruments (API™ 3200, 4000 and 5000 systems), the vacuum gauge pressure is expected to be higher, usually up to 4 x 10e-5 torr.

For current vacuum gauge pressure readings, double click on mass spectrometer icon at the bottom right corner of Analyst® software to open the MassSpec Detailed Status window. Under the Vacuum System Status section, the real-time readout for the vacuum gauge pressure is visible.

For vacuum gauge pressure values from older samples, navigate to the file information pane and look under the section Log Information from Devices at Start of acquisition.
