A calorimeter is a device that is very closely related to calorimetry, being used to measure the amount of heat energy that is either lost or gained during some chemical or physical process. 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 heat 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 its most basic form, a calorimeter is an enclosed, well-insulated chamber, filled with 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 combustion of specific reactions. The most commonly found use would be in food calorimeters which determining how many calories are in our food. Calorimetry can be applied to both solid and liquid fuel testing, explosives testing, the study of heat energy in academia, water treatment, and soil characterization to name a few.
Calorimetry Techniques, Advantages, & Costs
Adiabatic (Isothermal Titration Clorimeters)
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 heat 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. It is important to note that no adiabatic calorimeter is completely adiabatic. Isothermal titration calorimetry, which study the interactions of small molecules with large ones, is an example of an adiabatic technique.
When looking at exothermic or endothermic properties of a chemical reaction, a reaction calorimeter is used. These devices are comprised of an insulated jacket surrounding a reaction container. The temperature measurement device should be submerged within the container. There are four main subcategories for reaction calorimeters:
- Heat Flow: This method focuses on the heat flow as it passes across the reactor’s wall. This means that the heat 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 heat loss or gain of the process is controlled by the heating or cooling of the insulating jacket in this type. The heat transfer fluid is observed to determine any change in heat 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.
Constant Volume (Bomb Calorimeters)
Constant volume calorimeters, also known as bomb calorimeters, measure the heat energy of a reaction in an environment with a constant volume. These calorimeters are used to look at heat 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 a bomb calorimeter 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 (Styrofoam Calorimeters)
As the name indicates, constant pressure calorimeters provide 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. These calorimeters 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 (DSC)
These devices observe how changes in a material’s temperature alter its heat capacity. While using a known material and monitoring the change in heat capacity, phase and physical changes can be detected with accuracy. The speed and ease with which this thermal analysis technique can cause materials to hit these transition points is the reason why it is such a common calorimetry method. There are two approaches to DSC, heat flux DSC 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 thermal thermal 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 DSC, heat flux DSC compares the temperature difference between the sample and reference container as their temperatures change at a constant rate.
At its heart, calorimeters and calorimetry use known physical or environmental properties to find unknown thermal properties of materials. Each method of calorimeter changes a different known variable and observes how that changes the sample’s thermal energy. The many different types of methods and classifications of these types of equipment go to show how complex and specific thermal analysis can be.
Calorimetry 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. The labels of any drink or food product that show how many calories are in food are derived using calorimetry.
If you need a calorimeter, 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
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.
