THERMAL ANALYSIS

Thermal analysis is a branch of material science where materials are characterized based on the changes in their properties as a response to temperature. The methods available are distinguished with respect to the property being measured.

Thermogravimetric Analysis (TGA) is a technique used to measure the changes in weight of a sample during a controlled temperature program. Samples are heated to a high enough temperature so that components decompose into gas. Measuring the mass loss enables the determination of the percent mass of a substance in a sample. Other characteristics such as degradation temperatures, and moisture content can also be calculated.

Combined Thermogravimetric-Differential Scanning Calorimetry (TG-DSC) also known as Simultaneous Thermal Analysis (STA) is a technique used to simultaneously measure Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) on one and the same sample in a single instrument. This method enables tracking of dehydration and the onset of high temperature decomposition while revealing heat flow changes associated with solid state phase and melting transitions of the same sample.

Thermal Conductivity & Volumetric Heat Capacity (FOX50) testing measures the ability of a material to transfer heat. The ability to predict thermal performance is important to the construction, automotive and other industries where optimizing energy efficiency is crucial.


RHEOLOGY

Rheology is the study of the viscoelastic properties of liquids and solids. Rheology is often used to establish the relationship between deformation (strain) and force (stress) imposed during the production of polymeric materials and other industrially important substances such as food  and pharmaceuticals. The ability to measure the viscous component is important in determining properties such as impact resistance, and working in the linear viscoelastic range makes this technique sensitive to structure.

Dynamic Mechanical Analysis (DMA) is a technique used to measure the mechanical stiffness & damping properties of a wide range of materials. DMA is useful in studying the linear viscoelastic range of materials such as polymers which behave both as an elastic solid and an inelastic, or viscous fluid.

The Rotational Rheometer AR 2000ex  (ROTATIONAL RHEOMETER) is useful for determining the flow characteristics for fluids of any viscosity and polymer melts as well running creep recovery tests, and determining viscoelastic parameters as a function of stress, strain, frequency, temperature or time.


MICROCALORIMETRY

Calorimetric analyses accurately measure the rate of heat absorbed or evolved when a molecule of interest interacts with another molecule.

Nano-Isothermal Titration Calorimetry (Nano-ITC) is used for binding and kinetic studies on purified, dilute biological or organic samples. Substrate kinetic and ligand binding studies further the understanding of molecular interactions in many biomedical, pharmaceutical, and engineering applications.


UNIVERSAL TESTING MACHINE

These machines test a range of materials in tension, compression, flexure, shear, and peel modes, and are used to predict how a material will perform under these types of forces.

The Universal Testing Machine (Dual Column) is used for Material’s Testing of ceramics, paper products, composites, textiles, etc., and for Design Testing in biomedical research, construction, and consumer products.
