The Hiden TPD Workstation for UHV Thermal Desorption Studies
(Nanowerk News) The new TPD Workstation from Hiden Analytical is a complete
turnkey station for UHV temperature programmed desorption
studies and is suited to both quality control and to research
applications. Applicable technologies include photovoltaics,
metallurgy and semiconductor and thin-film studies.
The sample heating stage is fully programmable to 1000°C 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 fast, 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 1
sq.cm. The integrated Hiden TPD thermal analysis software
provides complete control of experimental protocols including
sample temperature, analyser parameters and data acquisition
and display. The TPD analysis routines include peak integration
and peak de-convolution, with real-time data views in 3D
illustrating species evolved both with temperature and with time.
The system is totally 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, aided by the three viewports and the
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.
