1.7 Product
Description
7ooonoso Instruction Manual
Introduction 1
The Tekmar™ 7000 Headspace Autosampler is a microprocessor-
controll~d automatic sampler that is designed to improve sensitivity/
precision in gas chromatographic
or Gel spectrometry analysis of volatile
compounds in a wide range
of samples.
The 7000 is built upon the "static" headspace (as compared to the "dy-
namic" purge and trap) sampling technique. The 7000 removes volatile
compounds from a non-volatile matrix and injects them into the gas chro-
matograph in vapor form.
Ingeneral terms, the instrument works like this:
• The sealed vial, containing the sample, is lowered into the
electrically-heated sample platen. The platen can hold and heat up to
12 vials simultaneously.
• During the heating time, the volatile compounds in the sample
partition into the vial's atmosphere, known as the "headspace."
• When the platen has reached the temperature setpoint -- and the rate
of analytes going into the gas phase is equal to the rate of analytes
returning -- the system reaches a state
of equilibrium.
• The vial is pressurized with gas to a setvalue.
• The gas in the sample vial exits through the sample loop to the
atmosphere, as the loop is filled with sample vapor.
• At equilibrium, the 7000 extracts the compounds (in vapor form)
from the headspace
of the vial, then injects them through the sample
transfer line into the gas chromatograph for analysis. During injection,
there is precise control
of sampling pressure, volume, and tempera-
ture, which greatly increases quantitation -- and therefore reliability --
of the sampling run.
With the Tekmar™ 7050 Carrousel installed, the 7000 can automatically
control the sample sequencing
of up to 50 vials. These samples can be
programmed to run under "Constant Heat Time™", a feature that provides
equal thermal exposure to each sample. Constant HeatTime reduces
overall analysis time and increases the number
of samples that can be run,
improving lab productivity.
The 7000's screen displays menus that allow you to choose from various
options for scheduling and editing methods, setting parameters,
testing internal components, etc.

1 Introduction
1-6
The optional TekLink™software/hardware package connects the 7000
to a PC and allows for complete remote control of the GC, data collec-
tion system, and the 7000. TekLink operates with Microsoft®
Windows™.
Additional standard features such as Method Optimization Mode™
allowyou to easily increment the optimal time, temperature, and mix
power settings for a given sampling run.
The 7000's "valve and loop" sampling design offers increased precision
and reproducibility
of injection volume. The exclusive PV rr Injector™
in the 7000 valve oven ensures precise control of injection pressure,
volume
and temperature.
Carryover is kept to a minimum because the 7000 automatically
performs a carrier-gas sweep to clean all sample lines between injec-
tions. Sample loops are interchangeable; the 7000 can accommodate
stainless steel, E-Form,
or Polar option sample loops in various sizes.
Flow elements are also interchangeable, giving you four different
ranges from one flow controller and the ability to set the optimal flow
rate best suited to your specific column type and size.

Introduction 1
The Tekmar™ 7000 Headspace Autosampler/7050 Carrousel system retains
sensitivity and precision in the analysis
of volatile components.
The 7000's primary applications are:
• Environmental screening of soils, water, and solid wastes
The 7000 is ideal for screening and direct analysis of priority
pollutants and
BTEX samples.
• Blood alcohol and forensic medicine
The 7000 ensures accurate identification and quantitation of
levels of ethanol, acetone, and other toxins in blood and
other biological samples.
• Monomers in polymers and residuals in food packaging
materials
Residuals in packing materials such as ethane, propane, and
propylene can
be easily and accurately quantitated.
• Residual solvents in pharamaceutical tablets and capsules
The 7000/GC process allows for routine monitoring of volatile
organic impurities in bulk pharmaceuticals and excipients.
• Flavors in foods and beverages
Flavor profiling determines the composition and taste of fruit,
wine, spices, coffee, soda, cheese, beer, and other foods and
beverages.
The static headspace technique around which the 7000 is designed
improves sensitivity
of the lighter compounds including HCN, S0
2,
butadiene, as compared to analysis of these compounds by liquid injection.
Static headspace technology is also ideal for semi-volatile organics such as
pyridine, di- and tri-chlorobenzenes, etc.
Through precise positioning and control of the heating process (as well as
through proper insulation), the 7000 maintains accuracy in sample tempera-
ture within 0.1
oc between samples.
Several
of the features built into the 7000, including Method Optimization
Mode™, Optimix™ Equilibration, Multiple Headspace Extraction, Re-
Equilibration, Constant Heat Time, and Full Evaporation Technique, also
help ensure optimal analytical results. All
of these features are discussed in
more detail in later sections
of this instruction manual.
If you have questions about the 7000/7050 as it relates to your particular
application, please call Tekmar at [phone] to speak with an
Applications Chemist.

2.1 Overview of
the Section
2.2 Warnings
7000!7050 Instruction Manual
Safety Information & Specifications 2
The first three pages of this section describe safety and operation issues
to be aware
of before operating the 7000/7050. The last part of Section 2
covers instrument specifications.
~ DANGER
Never connect a flammable gas (such as hydrogen) to
the pressurize bulkhead fitting on the rear of the 7000.
Venting ofthis gas in the Standby mode creates an
explosion or fire hazard.
~WARNING ~
Electrical shock hazard inside this instrument.
Unplug power cord before servicing.
~WARNING -·
It is recommended that safety glasses be worn at all
times when operating the 7000. Heated sample vials are
under pressure during normal operations. An inadvertent
over-pressurization
could cause a vial to burst.
~WARNING d.
This instrument contains heating elements. Touching
any heated zone during operation could cause a burn.
(The system's heaters will come on anytime their
setpoints
are above ambient temperature.) When
operating the 7000, keep all instrument panels fastened.
~ WARNING
The dust cover shipped with the 7050 (50-Position
Carrousel) must be installed before operating the
system. The cover protects the carrousel and also
protects the operator by providing a safety shield in
the event that an overpressurized vial would burst.

2 Safety Information & Specifications
2-2
£ WARNING
Be alert for environmental, shock, or other hazards in the
event that a vial would break inside the instrument. Before
cleaning up, unplug the instrument and determine the
nature of the sample that has spilled. Use extreme caution
and apply the appropriate clean-up measures.
£ WARNING d.
Always use the insert removal tool (Tekmar p/n
14-4365-027) when removing inserts from the platen. The
inserts are at the same temperature as the platen heater
and may cause a burn if handled improperly.
£ WARNING
Use extreme care when handling hot vials, particularly when
unloading vials from the 7000withoutthe 7050. Improper
handling of the hot vials may cause a burn.
£ WARNING __}
~
When the 7050 carrousel is indexing, do not place hands
between the carrousel and the valve oven area.
£ WARNING
Do not over-pressurize or over-heat samples during
operation. Extreme static pressure build-up in a vial due
to excess pressure levels or heat settings could cause a
vial toburst.
£ WARNING
When accessing the valve oven area, be certain that the
valve is cool before opening the cover.
