Introducing the ARES-G2
Overview
The TA Instruments ARES-G2 is a mechanical spectrometer capable of subjecting a sample to a dynamic
(sinusoidal) strain deformation, steady shear strain deformation, or a combination of dynamic and steady
strain. The ARES-G2 measures the resultant torque generated by the sample in response to this shear strain.
The figure below shows the ARES-G2 test station equipped with a forced convection oven. Shear strain is
applied by the motor; torque is measured independently by the transducer. Test parameters are set by the
operator, with the actual sample response determined by the motor and transducer.

The ARES-G2 works in conjunction with a controller, TA Instruments TRIOS software, and environmental
units to make up a rheological analysis system.
The controller is a computer that performs the following functions:
• Provides an interface between you and the instrument
• Enables you to set up experiments and enter parameters
• Runs the experiments and stores experimental data
• Allows you to calibrate the instrument
• Runs data analysis programs
The following pages provide a brief description of the components available with the system.
NOTE: For technical reference information, theory of operation, and other information associated with the
ARESG2 and not found in this manual, see the TRIOS online help.
