Delivering ultimate new capabilities for analyzing nonlinear and anisotropic rheology Orthogonal Superposition and 2D-SAOS
TA Instruments
About This Product
TA Instruments introduces a new dimension of rheology testing exclusively for ARES-G2. Angular and axial sinusoidal deformations enable all new capabilities to analyze nonlinear and anisotropic behavior of complex liquids. This new feature leverages the unique capabilities of ARES-G2 FRT to apply axial vibration perpendicular to angular shear.
■Features and benefits
・ARES-G2 rheometer-exclusive features made possible by patented FRT technology
・Unique test mode for quantifying steady shear state material properties and detecting microstructural anisotropy in the nonlinear regime
Specially designed double-gap concentric cylindrical geometry to minimize pumping effects and interfacial tension
・Fully programmable OSP and 2D-SAOS experiments with TRIOS software
・Simultaneous measurement in two directions
・Temperature control by Advanced Peltier System (APS)
■Orthogonal super position
Orthogonal superposition provides an excellent method for analyzing nonlinear viscoelasticity. A steady shear deformation in the angular direction is combined with an oscillatory deformation applied in the axial direction by the ARES-G2 FRT. Steady-state properties in the flow direction and dynamic properties perpendicular to the flow are measured. This flow is well controlled and the viscoelastic response can be easily interpreted.
■2D small amplitude vibration shear
2D-SAOS measures linear viscoelasticity with bidirectional selectivity. This is particularly useful in understanding the anisotropy of complex liquids. Simultaneous angular and axial oscillatory deformation generates angularly controlled linear vibrations or local rotational flows. This allows a good understanding of the anisotropy in a single oscillation period.
