Calorimetry is the act of measuring the change in energy of an object or system by observing the heat transfer that occurs with its surroundings. This heat exchange may occur due to physical changes, chemical reactions, or even sudden phase changes in the object or systems being monitored. When looking at chemical reactions, these thermal devices are able to determine if the reaction resulted in a loss of heat, an exothermic reaction, or if the reaction resulted in heat being absorbed, an endothermic reaction.

In calorimetry the device used to measure the change in thermal energy of either a chemical or physical process is called a calorimeter. If this process occurs at constant pressure, the change in heat measured is also known as the change in a system’s enthalpy. It can also be used to find the amount of energy required to raise the temperature of a system or object by one degree. This is known as finding a system’s heat capacity and is expressed as joules per kelvin (J/K). When heat capacity is expressed in calories per gram, this is referred to as specific heat. In their most basic form, these devices have an enclosed, well-insulated chamber, filled with a known reference material, water is widely used, and something that can measure the heat of the desired reaction inside the chamber.

Performing thermal analysis of materials has use in a wide variety of fields in chemistry, material science, and thermodynamics. Isothermal and isothermal titration calorimetry, for example, are laboratory devices that study thermal reactions in biological, physical, or chemical processes. Studying the thermal reactions between biomolecules is referred to a microcalorimetry. Bomb calorimeters are used to study combustions of specific reactions. The most commonly found use would be in food where these thermal reaction measuring devices are used to determine how many calories are in our food. These instruments can be useful in both solid and liquid fuel testing, explosives testing, the study of heat energy in academia, water treatment, and soil characterization.

Techniques, Advantages, & Costs of Calorimeters

Adiabatic (Isothermal Titration Clorimeters/ITC)
This thermal analysis technique is used to look at heat exchange inside a system without having any heat transfer to its surroundings. This type of process is referred to as adiabatic. Ideally, when energy is generated in this type of setup, 100% of that heat will go toward increasing the system’s temperature, feeding the reaction. The reaction would then generate more heat accelerating the increase in temperature, and thus, the reaction. These devices are used to study so-called “runaway reactions” for this reason. ITC is an example of an adiabatic calorimeter that is used to study the interactions of small molecules with large ones.

Reaction
When looking at exothermic or endothermic properties of a chemical reaction, reaction calorimeters are used. These devices are comprised of an insulated jacket surrounding a reaction container. A temperature measuring instrument is then submerged within the container. These devices can be separated into four main subcategories depending on what they are measuring and how they are measuring it.

  • Heat Flow: This method focuses on the heat flow as it passes across the reactor’s wall. This means that the energy input or output is transferred from the insulating jacked to the samples. This then can be used to determine the amount of heat per unit of area per unit of time, that is transferred. This is referred to as the heat flux.
  • Heat Balance: The thermal losses or gains of a process is controlled by the heating or cooling of the insulating jacket in this method. The heat transfer fluid is observed to determine any change in the energy of the system.
  • Power Compensation (PCC): A cooling jacket working at a constant temperature and a constant flow rate is used and the process temperature is controlled by adjusting the power being fed to an electrical heater. The power of the electrical heater is varied to maintain the desired temperature throughout the process.
  • Constant Flux: Maintaining a constant temperature of the insulated jacket, constant flux calorimetry instead varies the area that the heat transfer occurs over by varying the geometry of the jacket.

Bomb Calorimeter (Constant Volume)
This method involves measuring the heat energy of a reaction in an environment under constant volume conditions. This is why it is considered a constant volume calorimetry technique. They are used to look at thermal changes within a combustion reaction. Since the volume must remain the same, these devices are built to withstand immense pressure that increases while the reactions occur within them. The basic components that make up bomb calorimetry instruments are the sample, ignition wires to cause the reaction, and a “bomb”, a stainless steel container in which the reaction will occur, one which is often submerged in water and held inside an insulated container. Additionally, there is a thermometer and a stirrer that monitor and move the water in the container.

Constant Pressure Calorimetry
As the name indicates, this technique involves using a constant pressure environment to measure the change in a reactions enthalpy, a material’s aversion to change. A simple example would be what is known as a coffee cup calorimeter. They consist of two styrofoam coffee cups nested in one another with a lid on top that has a hole for the thermometer and a stirring rod. A known solvent (such as water) is stored inside the innermost cup. With the outer cup acting as an insulator, the heat from the reaction is absorbed into the solvent and measured with the thermometer. Constant pressure calorimeters are also called isobaric calorimeters.

Differential Scanning Calorimetry (DSC)
These devices observe how changes in a material’s temperature alter its heat capacity. While using a known material and monitoring the differences in heat capacity, phase and physical changes can be detected with accuracy. DSC’s ease with which it is able to cause materials to reach their transition points and the speed that these tests are done are why it is such a commonly used technique. There are two main approaches, heat flux and heat flow DSC.

  • Heat Flow: This device measures the flow of thermal energy into a sample in one container by comparing it to the flow of heat energy into a separate reference container. In both cases, the containers are kept at a constant temperature through the entire reaction.
  • Heat Flux: Similar to heat flow, heat flux DSC compares the temperature difference between the sample and reference container as their temperatures change at a constant rate.

At their heart, calorimeters  use known physical or environmental properties to find unknown thermal properties of materials. Each method changes a different known variable and observes how that changes the sample’s thermal energy. The many different types of techniques and classifications of these types of equipment go to show how complex and specific thermal analysis can be.

They can even be found in particle physics in the form of hadron and electromagnetic calorimeters. Both are used to better understand the smallest known units of matter in our universe by studying the heat energy of particles. A hadronic calorimeter is currently being used at the European Organization for Nuclear Research (CERN) in the study of the Higgs-Boson particle, however not every application is so complex. For example, the amount of calories listed on the nutrition labels of food are obtained using these thermal reaction devices.

If you need a thermal analysis instrument, for commercial or academic purposes, you should not need to worry about how you are going to finance it. Though they can be vital to your work, calorimeters can be prohibitively expensive, but that should not deter you from acquiring the equipment that you need. Excedr offers you a smart alternative to purchasing that allows you to continue your work in a fiscally responsible manner.

Lease Any Bomb Calorimeter That Suits Your Needs

Operating Lease

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.

Sale Leaseback

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.
