Computer acquisition and analysis of thermal profiles from differential scanning calorimeter

In this paper we describe a computerized system for data recovery from differential scanning calorimetry of mammalian cells and their biopolymers. The 'in-house'-designed preamplifier, digital acquisition, control card and its real-time software provide us with a powerful workstation to acquire and analyze large quantities of data on-line and off-line. The final data are obtained after eliminating noise interference using both hardware and software filters. Fourier analysis is also performed for a more refined thermodynamic characterization. All software is written in Basic and Fortran 77 under the DOS 3.10 operating system on a personal computer.
