Data obtained from thermal analysis equipment provides great insight into thermodynamic and mechanistic aspects of the thermal behaviour of materials and their interactions with probe molecules. Mass Spectrometry employed in conjunction with thermal analysis provides speciation of evolved species as function of temperature and time to provide an extremely powerful technique for the characterisation of materials and their interactions and reactions with their environment. In order to obtain the full benefits from a TA-MS coupling, it is vital that the interface is optimised to avoid dead volumes and cold spots that compromise system performance. Hiden software/hardware interfaces provide for seamless operation for the combined TA-MS system.

Hiden offers optimized interface coupling to a range of thermal analysis systems including :

TGA-MS and TGA/DTA-MS systems : Hiden Isochema IGA - intelligent gravimetric analyser, PerkinElmer, TA Instruments, Netzsch,  Mettler Toledo, Seteram

Calorimetry : Mass spectrometry for simultaneous evolved gas/calirometry analysis. Evolved gas analysis compliments the calorimetric data providing reaction kinetics data and speciation of reaction off gas.

Solid Insertion Probe: An integrated solid insertion probe mass spectrometer system for in-situ TPD studies.

Hiden CATLAB-PCS : An integrated microreactor/mass spectrometer for catalyst characterisation.
