In-situ Near Ambient Pressure Cell

  • E-beam heating possibility up to 600 °C at 20 mbar in N2, pressure tested at 40 mbar
  • Spare second Cell for exchange, special design for high temperatures up to 800 °C
  • Easy exchange of the In-situ NAP Cells
  • Small reaction volume
  • Sample cooling possibility with liqiud nitrogen down to 200 K at 20 mbar
  • Performance 4 to 7 times higher than postulated in the tendering procedure

Gas supply

  • Ar, N2, O2, H2 with a quality better 5.0 from the central gas supply
  • CO, CO2 from gas cabinets in the laboratory
