Part of Thermo Fisher Scientific
Nicolet x700 FT-IR
series spectrometer
with internal,
in-sample compartment
TGA accessory
The Thermo Scientific Nicolet
FT-IR spectrometer offers TGA-IR
capability to monitor real time
evolution of gases from a heated
sample with two user options –
an external TGA module, or an
internal, in-sample compartment
TGA accessory.
To better accommodate the varying needs of
laboratories, we offer users the choice of an
in-sample-compartment TGA accessory or an
external TGA module to couple with FT-IR to
identify evolved gases from thermogravimetric
measurements. TGA measures the change in
weight of a sample as a function of temperature
or time in a controlled atmosphere. This
change in weight is usually accompanied by
an evolution of gases caused by sample
decomposition or volatilization. Identification
of the components of the evolved gases helps
determine sample characteristics that cannot
be identified using TGA analysis alone.
TGA Compatibility
The TGA-IR Interface is compatible with
Seiko, TA Instruments, Mettler, and all
Thermo Scientific TGA systems. For
compatibility with other TGA systems,
please contact Thermo Scientific.
Product Specifications
The External TGA-IR module
The TGA-IR module gives users the convenience
of having a dedicated unit for TGA-IR
analysis without needing to remove the TGA
accessory from the sample compartment in
order to proceed with regular FT-IR analysis.
The design allows evolved gases to be
introduced to the gas cell through a very
short transfer line. The 100 mm stainless
steel gas cell is equipped with KBr windows
(with a ZnSe option) and has an internal
volume of 23 ml. The DTGS detector is
pinned in place and can be interchanged
with the bench detector without alignment.
OMNIC Series Software
The TGA-IR Interface uses Windows ® -based
OMNIC Series software. This software
provides an easy-to-use graphical interface
for the TGA-IR analysis with convenient
pull-down menus that simplify the learning
process and increase productivity.

Product Specifications
OMNIC Series software incorporates a
powerful real-time display of the total
infrared response (Gram-Schmidt reconstruct).
Additionally, fully processed infrared spectra
are displayed so you see exactly what
gases are evolving during the experiment.
You may isolate specific functional groups
in the evolved gases by selecting specific
window reconstructs, called Chemigrams .
The combination of the high-performance
TGA-IR Interface and OMNIC’s real-time series
data collect software provides outstanding
routine and research-level gas analysis.

Lock-in-Line connection to the right or
left side of Nicolet FT-IR spectrometers,
providing precise optical alignment of the

100 mm in length and 23 ml internal
volume with KBr windows; capable of
temperatures up to 325°C

steel transfer line connects directly to the
TGA furnace tube, providing a totally inert
passage of evolved gases into the gas cell

control of TGA cell and transfer line
temperature; software selectable from
ambient to 325°C
Detector: a DTGS detector is recommended
for typical TGA-IR experiments, and
provides excellent sensitivity, a spectral

linearity for quantitative analysis; an
optional MCT-B detector is available for
high-speed evolved gas analysis;

The Internal (in-samplecompartment)
TGA-IR Accessory
The TGA-IR Interface for Nicolet FT-IR
spectrometers is connected to the TGA
instrument via a heated transfer line. As
gases evolve during the TGA experiment,
they pass into the flow cell of the TGA-IR
Interface where the infrared spectra are
collected. The flexible design of the interface
allows it to be placed in the sample compartment
of the Nicolet FT-IR spectrometer
or in an Auxiliary Experiment Module (AEM).
The AEM can be attached to either right or
the left side of the spectrometer, making it
compatible with almost any laboratory
equipment configuration.
Optimized for use with high flow rates,
the TGA flow cell is compatible with all
types of evolved gases and materials. The
cell’s large inside diameter provides high
throughput and eliminates spectral interference
caused by deposits on the walls. The
flow cell is also spring loaded and easily
removed from the heated module for cleaning.
Optics/Hardware for In-sample
Compartment
Module: the compact, flexible design fits
into any sample compartment of a Nicolet
FT-IR spectrometer, including a right or
left side AEM; the interface is pre-aligned
on a sample compartment base-plate for
easy installation without alignment
Optics: an efficient optical path uses three
reflective optical elements to direct the IR
beam through the interface; the beam
path provides a 17 cm pathlength for high
sensitivity
Flow Cell: the 27 mm inside diameter
glass flow cell provides greater than 40%
throughput compared to the open beam
sample compartment; the total cell volume
of 49 ml is consistent with typical TGA
purge flow rates of 50 – 100 ml/min
Transfer Line: a glass-lined stainless steel
transfer line connects directly to the TGA
furnace tube, providing a totally inert
passage way for evolved gases into the
glass TGA flow cell
