iv
Safety considerations
Some reagents and samples used with Waters instruments and devices can
pose chemical, biological, and radiological hazards. You must know the
potentially hazardous effects of all substances you work with. Always follow
Good Laboratory Practice, and consult your organization’s safety
representative for guidance.
Considerations specific to the Xevo TQ-S system
Solvent-leakage hazard
The source exhaust system is designed to be robust and leak-tight. Waters
recommends you perform a hazard analysis, assuming a maximum leak into
the laboratory atmosphere of 10% LC eluate.
Flammable-solvents hazard
Never let the nitrogen supply pressure fall below 400 kPa (4 bar, 58 psi)
during analyses that require flammable solvents. Connect to the LC output
with a gas-fail connector to stop the LC solvent if the nitrogen supply fails.
Warning:
• To confirm the integrity of the source exhaust system, renew
the source O-rings at intervals not exceeding one year.
• To avoid chemical degradation of the source O-rings, which can
withstand exposure only to certain solvents (see “Solvents used
to prepare mobile phases” on page C-3), determine whether any
solvents you use that are not listed are chemically compatible
with the composition of the O-rings.
Warning: To prevent the ignition of accumulated solvent vapors inside
the source, maintain a continuous flow of nitrogen through the source
whenever significant amounts of flammable solvents are used during
instrument operation.

v
Glass-breakage hazard
High-temperature hazard
Mass spectrometer high-temperature hazard:
Warning: To avoid injuries from broken glass, falling objects, or
exposure to toxic substances, never place containers on top of the
instrument or on its front covers.
Warning: To avoid burn injuries, avoid touching the source ion block
assembly when operating or servicing the instrument.

vi
Hazards associated with removing an instrument from service
When you remove the instrument from use to repair or dispose of it, you must
decontaminate all of its vacuum areas. These are the areas in which you can
expect to encounter the highest levels of contamination:
• Source interior
• Waste tubing
• Exhaust system
• Rotary pump oil (where applicable)
The need to decontaminate other vacuum areas of the instrument depends on
the kinds of samples the instrument analyzed and their levels of
concentration. Do not dispose of the instrument or return it to Waters for
repair until the authority responsible for approving its removal from the
premises specifies the extent of decontamination required and the level of
residual contamination permissible. That authority must also prescribe the
method of decontamination to be used and the appropriate protection for
personnel undertaking the decontamination process.
You must handle items such as syringes, fused silica lines, and borosilicate
tips used to carry sample into the source area in accordance with laboratory
procedures for contaminated vessels and sharps. To avoid contamination by
carcinogenic, toxic, or biohazardous substances, you must wear
chemical-resistant gloves when handling or disposing of used oil.
Safety advisories
Consult Appendix A for a comprehensive list of warning and caution
advisories.
Warning: To avoid personal contamination with
biohazardous or toxic materials, wear chemical-resistant
gloves during all phases of instrument decontamination.
Warning: To avoid puncture injuries, handle syringes, fused silica lines,
and borosilicate tips with care.

Intended use of the Xevo TQ-S
Waters designed the Xevo™ TQ-S to deliver accurate, reproducible and robust
quantification of target compounds at the lowest possible levels in highly
complex sample matrices. It can be used for general in vitro diagnostic
applications.
Calibrating
To calibrate LC systems, follow acceptable calibration methods using at least
five standards to generate a standard curve. The concentration range for
standards should include the entire range of QC samples, typical specimens,
and atypical specimens.
When calibrating mass spectrometers, consult the calibration section of the
operator’s guide for the instrument you are calibrating. In cases where an
overview and maintenance guide, not operator’s guide, accompanies the
instrument, 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. 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.
When analyzing samples from a complex matrix such as serum/plasma, whole
blood, and other sources, note that the matrix components can adversely affect
LC/MS results, enhancing or suppressing ionization. To minimize these
matrix effects, Waters recommends you adopt the following measures:
• Prior to the instrumental analysis, use appropriate sample
pretreatment such as protein precipitation, liquid/liquid extraction
(LLE), or solid phase extraction (SPE) to remove matrix interferences.
The Waters Xevo TQ-S is CE-marked according to the European
Union In Vitro Diagnostic Device Directive 98/79/EC.

ix
• Whenever possible, verify method accuracy and precision using
matrix-matched calibrators and QC samples.
• Use one or more internal standard compounds, preferably isotopically
labeled analytes.
ISM classification
ISM Classification: ISM Group 1 Class A
This classification has been assigned in accordance with IEC CISPR 11
Industrial Scientific and Medical (ISM) instruments requirements. Group 1
products apply to intentionally generated and/or used conductively coupled
radio-frequency energy that is necessary for the internal functioning of the
equipment. Class A products are suitable for use in commercial, (that is,
nonresidential) locations and can be directly connected to a low-voltage,
power-supply network.

1-2 Waters Xevo TQ-S Overview
Waters Xevo TQ-S
The Waters®Xevo®TQ-S is a tandem quadrupole, atmospheric pressure
ionization (API) mass spectrometer. Designed for routine HPLC/MS/MS and
UPLC®/MS/MS analyses in quantitative and qualitative applications, it can
operate at fast acquisition speeds compatible with UltraPerformance LC®.
For mass spectrometer specifications, see the Waters Xevo TQ-S Site
Preparation Guide.
Waters Xevo TQ-S:
IntelliStart technology
IntelliStart™ technology monitors LC/MS/MS performance and reports when
the mass spectrometer is ready for use.
TQ-S

Waters Xevo TQ-S 1-3
The IntelliStart software automatically tunes and mass calibrates the mass
spectrometer and displays performance readbacks. Integrated with
MassLynx™ mass spectrometry software and Instrument Console software,
IntelliStart software enables simplified setup of the system for use in routine
analytical and open access applications (see “Software and data system” on
page 1-5).
The IntelliStart Fluidics system1is built into the mass spectrometer. It
delivers sample directly to the MS probe from the LC column or from three
integral reservoirs. The integral reservoirs can also deliver sample through
direct or combined infusion so that you can optimize instrument performance
at analytical flow rates.
Recommendation: Use reservoir A for the calibrant solution, reservoir B for
tuning compounds, and reservoir C for analyte/optimization solution.
A fourth reservoir contains solvent for automated flushing of the solvent
delivery system.
See the mass spectrometer’s online Help for further details on IntelliStart
technology.
ACQUITY UPLC/MS Xevo TQ-S systems
The Waters Xevo TQ-S is compatible with the ACQUITY UPLC®systems; if
you are not using an ACQUITY UPLC system, refer to the documentation
relevant to your LC system (see “Non-ACQUITY devices for use with the Xevo
TQ-S” on page 1-4).
ACQUITY UPLC system
The ACQUITY UPLC system includes a binary solvent manager, sample
manager, column heater, optional sample organizer, optional column
manager, optional detectors, and a specialized ACQUITY UPLC column.
WatersMassLynx mass spectrometry software controls the system.
For further instruction, see the ACQUITY UPLC System Operator’s Guide or
Controlling Contamination in LC/MS Systems (part number 715001307). You
can find these documents on http://www.waters.com; click Services and
Support > Support.
