Windows Software for Thermoanalysis

We offer a computer-based measurement and evaluation software package for our thermoanalytical equipment. The system is controlled with a PC compatible computer. Optionally a color plotter can be connected to draw the measured curves. We recommend the use of a color Ink-jet printer. The software is easy to handle. The user is guided step by step through the menu driven program. Help information is available for all functions.

The incoming data is displayed on the screen in Realtime. All functions are activated via function-keys or mouse click.

• EGA / VGA video mode
• Multitasking
• Mouse control
• Free comments
• Complete documentation with color printout and evaluation list
• Data export to other programs
• Temperature control including heating up, cooling down and isothermic experiments
• Computer controlled automatic calibration
• Automatic baseline correction
• Realtime display of the ongoing process
• Evaluation includes peak temperature, peak area, enthalpy, glass transition point and onset temperature
• Curve smoothing
• Zoom function for any curve section multiple curves can be displayed simultaneously to be compared
• Arithmetic functions to add, subtract and differentiate curves, also multiplication and division
• Standardizing of sample weight
