Abstract
The design, development and calibration of a novel analytical reaction microcalorimeter is described. The instrument uses a modified Teflon stopcock as the reaction chamber, an aluminum block with built-in syringes as the equilibrium chamber and a thermistor bead as the detector. Operational amplifiers are used for signal amplification. The reaction of two thermally equilibrated reagents occurs inside the reaction chamber. Using microliter quantities of reagents, the microcalorimeter is sensitive to energy changes in the order of millicalories per mole.
