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 TQ Detector
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 690 kPa (6.9 bar, 100 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
the instrument’s operation.
Warning: To avoid unmanaged solvent spillage, do not place tools
or other objects in the drain channel on the probe top. Keep the
channel free from blockages.

Safety advisories
Consult Appendix A for a comprehensive list of warning and caution
advisories.
Warning:
• To avoid electric shock, do not remove the TQ Detector’s protective
panels. The components they cover are not user-serviceable.
• To avoid non-lethal electric shock, any equipment connected to the
ESI and IonSABRE™ APCI probes must be grounded.
• To avoid nonlethal electric shock when the instrument is in
Operate mode, avoid touching the areas marked with the high
voltage warning symbol. To touch those areas, first put the
instrument in Standby mode.

vii
Operating this instrument
When operating this instrument, follow standard quality-control (QC)
procedures and the guidelines presented in this section.
Applicable symbols
Intended use
Waters designed the TQ (for tandem quadrupole) Detector for use as a
research tool to deliver authenticated mass measurement in both MS and
MS/MS modes. This Tandem Quad (TQ) Detector is for research use only and
is not intended for use in 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 must cover the entire range of quality-control samples, typical
specimens, and atypical specimens.

viii
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 quality-control samples that represent subnormal,
normal, and above-normal levels of a compound. Ensure that quality-control
sample results fall within an acceptable range, and evaluate precision from
day to day and run to run. Data collected when quality-control samples are
out of range might not be valid. Do not report these data until you are certain
that the instrument performs satisfactorily.

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 TQ Detector
Overview
Waters TQ Detector
The Waters®TQ Detector is a tandem quadrupole, atmospheric-pressure,
ionization (API) mass spectrometer. Designed for routine UPLC™/MS/MS
analyses in quantitative and qualitative applications, it can operate at fast
acquisition speeds compatible with ultra-performance liquid-chromatography
(UPLC).
Waters provides these ion sources with the instrument as standard
equipment:
• ZSpray™ (dual orthogonal sampling) interface.
• Multi-mode ESCi®ionization switching for atmospheric pressure
chemical ionization (APCI) and electrospray ionization (ESI).
Optional ionization modes are IonSABRE™ APCI and APPI (atmospheric
pressure photoionization).
For instrument specifications, see the Waters TQ Detector Site Preparation
Guide.

IntelliStart technology
IntelliStart™ technology monitors LC/MS/MS performance and reports when
the instrument is ready for use.
The software automatically tunes and mass calibrates the instrument and
displays performance readbacks. Integrated with Empower™
chromatography software, MassLynx™ mass spectrometry software, and
ACQUITY UPLC®Console software, it 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 system is built into the instrument. It delivers
sample directly to the MS probe from the LC column or from two 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. See the instrument’s online Help for further details of
IntelliStart.
ACQUITY TQD UPLC/MS system
The ACQUITY TQD UPLC/MS system includes an ACQUITY UPLC system
and the Waters TQ Detector.
If you are not using your instrument as part of an ACQUITY UPLC system,
refer to the documentation for your LC system.
ACQUITY UPLC system
The ACQUITY UPLC system includes a binary solvent manager, sample
manager, column heater, optional sample organizer, optional detectors, and
an ACQUITY UPLC column. WatersEmpower™ chromatography software or
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 the documents on http://www.waters.com.
