1-2 Waters Xevo G2 QTof Overview
Waters Xevo G2 QTof
The Xevo™ G2 QTof Mass Spectrometry (MS) system is a hybrid, quadrupole,
orthogonal acceleration, time-of-flight (oaTOF) mass spectrometer operated by
Waters
®
informatics software.
Either of the following high-performance, ZSpray™, dual-orthogonal, API
sources is fitted as standard equipment:
• LockSpray™ electrospray ionization/atmospheric pressure chemical
ionization/combined electrospray ionization and atmospheric pressure
chemical ionization (ESI/APCI/ESCi
®
) source, see “LockSpray source
and ionization modes” on page 1-6 .
• NanoLockSpray™ ESI source, see “NanoLockSpray source and
ionization modes” on page 1-9 .
You can also use the optional combined APPI/APCI source with the
Xevo G2 QTof (see the Waters APPI Source Operator’s Guide Supplement ).
For the instrument’s specifications, see the Waters Xevo G2 QTof Site
Preparation Guide .
IntelliStart technology
IntelliStart technology monitors instrument performance and reports when it
is ready for use.
The console software automatically mass calibrates the mass spectrometer
and displays performance readbacks to enable simplified setup of the system
for use in routine analytical and open access applications.
The IntelliStart Fluidics
1
system is built into the mass spectrometer. It
delivers sample directly to the MS probe from the LC column or from three
integral reservoirs. The reservoirs can also deliver sample through direct or
combined infusion so that you can optimize instrument performance at
analytical flow rates. An additional reservoir contains solvent for the
automated flushing of the solvent delivery system.

pathways within and between instruments and devices.
