• Process monitoring
• Process control

Simultaneous thermal analysis (STA) is a combined measurement of thermogravimetry (TGA) and differential scanning calorimetry (DSC). This allows STA to determine both the temperature-dependent mass change and the caloric effects using DSC in a single measurement. Using the example of the measurement of titanium hydride, it can be shown how much hydrogen is released as a function of the temperature change. In addition, the desorption peaks are recorded by the DSC.

Requirements

In order to create optimum measuring conditions for every application, the devices are designed to be vacuum-tight and allow pressures of up to 1e-5 mbar to be generated. To ensure consistent measuring conditions, it is essential that the vacuum is monitored and controlled during the measurement.

Suitable Products

Depending on the pressure range of the system, the VSM77D or the VSP63DL are used to control and regulate the vacuum in the sample chamber, enabling optimum measuring conditions.

VSM77D: In the VSM digital vacuum transducer, a combination of a Pirani and a cold cathode sensor measures absolute pressure from atmosphere to ultra-high vacuum. The automatic switching on and off of the cold cathode by the Pirani sensor at low pressure extends the service life. Overpressure resistance up to 16 bar.

VSP63DL: The processor-controlled Pirani transducer VSP with robust helix filament is ideally suited for precise measurements in the fine vacuum range. The optimized temperature compensation ensures stable measured values.
