TPD/TDS system

Stand-alone system intended for measuring adsorption/desorption of ultrathin films, capable of high precision temperature control over a wide temperature range.

  • One level TPD/TDS chamber with base pressure 1×10-9 mbar (spare ports available for additional components)
  • Equipped with quadrupole TDS 40A1 Thermal Desorption Spectrometer (Mass range up to 200 AMU) on Z shift for optimal detector positioning
  • Specially designed conical sampling end piece
  • 1-axis UHV manipulator with high precision temperature control over a wide temperature range (-170 °C to 1200 °C)
  • Computer-controlled data acquisition and processing software for TDS
  • Load Lock chamber for two PTS sample holders
  • Reliable and fast linear transferring system from load-lock to TPD chamber
  • 19“ cabinet for all electronic units
  • Adjustable rigid main frame with large wheels for easy placement of the system

Many upgrade options available, e.g.:

  • Additional axes of movement and full motorisation of the manipulator
  • Possibility to extend pressure range from UHV up to 1 atm with precise PLC control of the pressure
  • Gas dosing system (manual or precise with PLC control)
  • Solvent dosing system
  • Sample holders dedicated to work in corrosive environment
  • Heating and LN2 cooling option for the load lock
  • Dedicated chamber for sample preparation
  • Residual gas analyser for a different mass range

Applications:

  • Surface science
  • Nanoparticles
  • Thin films
  • Semiconductors
  • Photovoltaics
  • Materials characterisation
