LED
Lit when the system is powered up.
Power
Green
Lit when the correct vacuum level has been
achieved. Flashing if the vacuum is not at the
correct level (during pump down and venting).
Vacuum
Green
Lit when the system is in the Ready state. The
system must be in the Ready state to operate.
Ready
Green
Flashing when the system is acquiring data.
Scanning
Blue
Lit when the system encounters a system fault.
Fault
Red
After the system is turned on, the power LED illuminates, and the fault LED flashes for a few seconds. Then the
vacuum LED begins to flash. After the correct vacuum level is achieved, this LED remains lit.
Theory of Operation
Mass spectrometry measures the mass-to-charge ratio of ions to identify and quantify compounds.
The SCIEX X500 QTOF system has a series of quadrupole filters that transmit ions according to their mass-to-charge
(
m/z
) value. The first quadrupole in this series is the QJet
®
ion guide, which is located between the orifice plate
and the Q0 region. The QJet
®
ion guide does not filter ions, but focuses them before they enter the Q0 region. By
prefocusing the larger ion flux created by the wider orifice, the QJet
®
ion guide increases instrument sensitivity
