"Thermal analysis data stations Software - (TADS) system" are used for interfacing with thermal analysis instruments. It consists of a Windows based software package and a dedicated hardware module for acquisition of experimental data. This System is not specific to any particular instrument make or model. TADS couples to the instrument non-invasively and in parallel by tapping the low level analog signals at the recorder points and acquiring data through a hardware module which handles signal conditioning, digital conversion and communication with the PC. In rare cases; where no analog signal tap exists in any form, the software package can still be utilized through a file exchange utility for processing of spectral data separately. Thus, the hardware module is optional.

TADS can acquire three signals at a time: Temperature, DTA/DSC/TMA and TG and it generates derivative profile of one primary signal internally. Extensive data acquisition, analysis and presentation features are provided in the Microsoft Windows based software. It is possible to do file analysis of experiment data with the acquisition running in the background.

MAIN FEATURES

• Acquisition of three signals: Temperature, DTA or DSC or TMA and TG, with a derivative profile generated internally
• Concurrent processing of filed spectra with data acquisition in the background
• ASCII import/export for external compatibility
• Software linearization for different thermocouples
• Selectable sampling rate from 0.5 sec to 60 sec
• Multiple sampling for noise reduction

APPLICATIONS

• Thermo-analytical techniques (DTA, DSC, TG and TMA) have been used extensively in diverse areas in chemical and metallurgical engineering, chemistry and materials science for quality assurance, process and product development as well as basic research
