The sample heating stage is fully programmable to 1000ºC and is mounted within a stainless steel bellows-sealed linear drive for precise sample positioning close to the mass spectrometer analyser.
The system features the Hiden 3F/PIC quadrupole with pulse ion counting detection for highest sensitivity together with data collection rates in excess of 500 data points per second. The close sample-to-analyser proximity ensures high collection efficiency and enables routine operation with sample size of just 1cm2, the company says.
Integrated Hiden TPD thermal analysis software controls experimental protocols including sample temperature, analyser parameters and data acquisition and display. The TPD analysis routines include peak integration and de-convolution, with realtime data views in 3D illustrating species evolved both with temperature and time.
The system is UHV compatible, with a fast sample load lock and easy-glide magnetic transfer mechanism for ultimate vacuum integrity. Positive sample placement is directly onto the horizontal heater surface, which is assisted by three view ports and a high-intensity illuminator. A thermocouple contacts directly to the sample for positive thermal control, and internal water-cooled heat shields inhibit degassing due to radiant heat.
