It mainly consists of a metallic vessel made of materials which are good conductors of electricity such as copper and aluminium etc. The temperature change, along with the specific heat and mass of the solution, can then be used to calculate the amount of heat involved in either case. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. TYPES OF DSC INSTRUMENTS: DSC HAS TWO TYPES OF INSTRUMENTS 1 .Heat - 1 Heat - flux DSC flux DSC Sample holder: PLATINUM,ALUMINIUM,STAINLESS STEEL. It permits the simultaneous measurement of heat effects that respond to a changing heating rate (reversing) and that don't respond to the changing heating rate (non-reversing). C There is also a facility for stirring the contents of the vessel. There is just one opening through which a thermometer can be inserted to measure the change in thermal properties inside. It is intended for use with the TAM IV thermostat to increase the sample throughput. The semi-adiabatic (isoperibol) calorimeters measure temperature changes up to 106C and account for heat loss through the walls of the reaction vessel to the environment, hence, semi-adiabatic. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. One of the first ice calorimeters was used in the winter of 1782 by Lavoisier and Pierre-Simon Laplace, which relied on the heat required to melt ice to water to measure the heat released from chemical reactions.[3]. The bomb is filled with the substance to be tested and an oxygen gas, and then sealed. 1.89 in.
