Simultane Thermoanalyse / simultaneous thermal analysis

Benefits VSM at a glance

  • Wide range combi sensor Pirani / cold cathode
  • Automatic control of the cold cathode by the Pirani, switch-on of cold cathode at low pressure increases lifetime, insensitive against inrush of air
  • Excellent ignition behavior
  • Low stray magnetic field
  • Overpressure stability up to 16 bar

Simultaneous thermo analysis

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.

Challenge

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.

Solution

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.
