Calorimeter And Method For Simultaneous Measurement Of Thermal Conductivity And Specific Heat Of Fluids

The present invention is a novel calorimeter and calorimetry apparatus and method for the ultrasensitive simultaneous measurement of heat capacity and thermal conductivity of fluids. The unique simultaneous measurement of the two parameters avoids sources of error seen in other methods. The calorimeter shows excellent accuracy of 1 part in 10,000 and run-to-run variability of 1 part in 100,000, as well as excellent long-term reproducibility. The invention is well suited for the study of biomaterials, such as lipids and proteins and other colloidal systems, which are not easily analyzed using conventional commercial instruments.
