A simple control method is increasing or decreasing the temperature at a constant rate, referred to as linear heating/cooling. The analysis is done by recording multiple measurements of the same material at different temperatures, also known as a stepwise isothermal measurement. Having the rate of change in temperature oscillate or having the heating or cooling rate change in response to alteration in the sample would be two examples of other, more complicated, control techniques. These can also be referred to as modulated temperature thermal analysis and sample controlled thermal analysis, respectively.
Thermal analyzers are used in material science, pharmaceutical processes, polymer analysis, medical research, and quality assurance. Their ability to ascertain physical qualities of a material in relation to changes in temperature make them indispensable to these fields. Additionally, the analysis can also look at a dielectric material’s electrical discharge, a stressed sample’s mechanical relaxation, measure a sample’s thermal conductivity or diffusivity, or any light or sound emissions, all in relation to changes in temperature. These instruments monitor endothermic and exothermic processes such as melting, boiling, sublimation, phase transition, crystallization, oxidation, and desolvation.
Thermal Analyzer Methods, Benefits, & Cost
Conducted by thermogravimetric analyzers, this methodology continuously measures the mass of a sample’s temperature changes over time. The result of TGA analysis is a plot of mass as a function of either time or temperature. These devices consist of a lab balance with the desired sample on it contained within a temperature controllable furnace. These analyzers are also known as thermobalances. TGA analysis is used in determining a materials thermal stability, oxidation, and combustion mass losses, in addition to the thermal decomposition present in pyrolysis and computation of materials.
Observing dimensional changes in materials as a function of temperature or time is done using a thermomechanical analyzer. This is considered a subdiscipline of thermomechanometry, another term for this technique. The sample is placed inside a furnace and a force generator is attached to it. The generator is used to deform the sample either by compression, tension, flexure, or torsion, and that all changes are measured and recorded. The constant application of force or non-oscillating stress deforms the sample over time. Expansion/compression, penetration, or tension probes are used depending on what type of measurement is needed.
Dielectric Thermal Analysis (DETA)
A thermoanalytical technique that measures the temperature of a substance as it is heated or cooled at a specific rate is DTA. Simultaneously a known reference inert material undergoes an identical thermal cycle and its temperature is also recorded. The difference between the two temperatures is plotted against either time or temperature and this plot then is used to determine other properties of the substance. This curve can then be used to plot exothermic and/or endothermic changes in the substance to identify transformation temperatures or when it melts, sublimates, and crystallizes. DTA’s ability to identify these transition points make it extremely useful for material identification. Differential thermal analysis is found in pharmaceutical, mineralogical, and environmental fields.
Differential Thermal Analysis (DTA)

Simultaneously a known reference inert material undergoes an identical thermal cycle and its temperature is also recorded.

DTA’s ability to identify these transition points make it extremely useful for material identification. Differential thermal analysis is found in pharmaceutical, mineralogical, and environmental fields.
Dynamic Mechanical Analysis (DMA or DMTA)
Similar to thermomechanical analyzers, dynamic mechanical analyzers look at a material’s dimensional changes as a function of time, temperature, and frequency of stress. As the frequency of the strain that is applied varies, the resulting stress on the material is measured. This sinusoidal force is applied by a probe that deforms the material and the relationship between the force applied and the deformation is also measured. When testing polymer materials, different deformation techniques are used depending on the force that needs to be measured. Tension, compression, dual cantilever bending, three-point bending, and shear modes are examples of a few techniques.
Dilatometry is the technique used to measure dimensional changes in a sample’s volume as changes in temperature occur. A simple and well-known dilatometer is a mercury-in-glass thermometer. As the mercury heats up, its volume expands at a measurably consistent rate. DILs can be subdivided into several types:
- Capacitance: The sample is placed between two parallel plates, one stationary and one movable. As the sample’s temperature changes and its length changes, it will move one plate, changing the gap between them.
- Connecting Rod (Push Rod): The pushrod is touching the sample which is placed inside a furnace. The thermal expansion is then measured by a strain gauge which charts the change in shape.
- High Resolution (HR) – Laser: Dimensional variations that are a result of temperature changes are quantified using light interference. The most accurate method of laser dilatometer is Michelson Interferometer type Laser Dilatometer.
- Optical: Uses high-resolution cameras to capture images of the material as it undergoes dimensional changes, achieving non-contact measurements.
Thermal analysis’ use of equilibrium thermodynamics, irreversible thermodynamics, and kinetics concepts allow it to be an effective tool that is used in both academic and professional fields. Material science, geology, quality assurance, heat transfer, and the pharmaceutical industry are just some examples. Though they are used as independent devices, thermal analyzers can also be combined with other measurement and testing devices to provide a more comprehensive testing system. Their range of base range of applications and their ability to couple with other devices means that thermal analyzers are extremely prevalent in many applications. In fact, this analysis method is now being used in interstellar applications.
Putting materials into space poses interesting problems due to the lack of an atmosphere. Additionally, reentry into the earth’s atmosphere poses unique issues when materials are exposed to extreme temperatures. NASA has had to perform extensive thermal analysis on its Earth Entry Vehicles (EEV) specifically to avoid any damage to the EEV for the Mars Sample Return mission. It would be an absolute tragedy if after all the time it took for those samples to return back to Earth ended with them burning up on reentry.
Whatever your thermal testing needs, terrestrial or otherwise, we can get you the equipment needed. Your main focus and energy should be on your work rather than worrying about how you are going to acquire or pay for that thermal analyzer that you need. Let Excedr help you save money with our leasing program and give your organization peace of mind.
We Offer Thermogravimetric System Leases to Fit Every Need
This off-balance sheet financing structure provides three options at the end of the term. The lessee has the option to return the equipment to the lessor, renew at a discounted rate, or purchase the instrument for the fair market value. Monthly payments are also 100% tax deductible which yields additional monetary savings.
If you recently bought equipment, Excedr can offer you cash for your device and convert your purchase into a long-term rental. This is called a sale leaseback. If you’ve paid for equipment within the last ninety days, we can help you recoup your investment and allow you to make low monthly payments. This also frees up money in your budget rather than tying it down to a fixed asset.
