Temperature Programmed Desorption

Temperature Programmed Desorption

Temperature Programmed Desorption (TPD) is one of the most widely used surface analysis techniques available for materials research scientists. To analyze material compositions, surface interactions and surface contaminates, scientists rely on Extrel’s Mass Spectrometry systems such as the VeraSpec Thermal Desorption System (TDS). Our thermal desorption systems are full stand-alone TPD systems that can accommodate samples up to 35 mm square, and can reach sampling temperatures of 500°C. They combine high sensitivity with precise control to provide the most accurate desorption analysis systems available.

In addition, Extrel MAX Series and MAX-LT™ Flange Mounted Mass Spectrometers can be used to add high sensitivity and high resolution TPD capability to any system already in use.

Extrel’s TPD products include:
