Audience and purpose

This guide is for operators of varying levels of experience. It gives an overview of the device and
explains how to prepare it for operation, change its modes of operation, and maintain it.

Intended use of the Xevo G2-XS QTof

Waters designed the orthogonal acceleration, time-of-flight Xevo G2-XS QTof for use as a
research tool to deliver authenticated mass measurement. The Xevo G2-XS QTof is for research
use only and is not intended for use in diagnostic applications.
Calibrating
To calibrate LC systems, adopt acceptable calibration methods using at least five standards to
generate a standard curve. The concentration range for standards must include the entire range
of QC samples, typical specimens, and atypical specimens.
When calibrating mass spectrometers, consult the instrument's online Help system for calibration
instructions.

Quality control

Routinely run three QC samples that represent subnormal, normal, and above-normal levels of a
compound. If sample trays are the same or very similar, vary the location of the QC samples in
the trays. Ensure that QC sample results fall within an acceptable range, and evaluate precision
from day to day and run to run. Data collected when QC samples are out of range might not be
valid. Do not report these data until you are certain that the instrument performs satisfactorily.
