A few calorimeters have a double active control in addition to the automatic cancellation of 7s - Tr by control of the thermostat temperature Ti, there is also an automatic cancellation of the temperature difference between the sample and a reference (which also forms part of the system S) by supply of heat to the cooler side. The first control is to provide the adiabatic conditions, whereas the second control is to provide a heat compensation of the phenomenon studied. The measurement of heat is not derived from a temperature increase of the system but from the electrical energy provided for the compensation. This principle was followed by Clarebrough [28], Bonjour [29] and Privalov [30].

Measurements were carried out using a Privalov-type calorimeter (see Section 2.2.2) which has sufficiently high resolution and stability to measure the partial heat capacity of the protein in a dilute... 

Other adiabatic calorimeters used for polymer heat capacity measurements have been described by Popov and Kolesov (1956) Warfield, Petree, and Donovan (1959) Hellw e, Knappe, and Wetzel (1962) Burdzhanadze, Privalov, and Tarvkhelidze (1963) Nolting (1983) Hager (1964) Braun, Hellwege, and Knappe (1967) and Grewer and Wilski (1968).
