• 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
• Fully UHV compatible gas purification system, controlled by SPECS software
• Ozon generator
• Optical Chilled Mirror controlled humidity calibration systems for humidification of the process gases
• Well-thought-out valve assemble which allows the purging of the Near Ambient Pressure Cell with gases and vapor
• Evacuable and bakeable gas lines

High-Pressure/High-Temperature Cell

• Halogen lamp for sample heating
• Chamber-in-chamber design with water cooled inner chamber, small reaction volume
• Thermal Mass Flow Controllers and Pressure Controller, implemented in SPECS software
• Small reaction volume
• Sample temperatures up to 600 °C for He and H₂ and up to 800 °C for all other gases at pressures up to 20 bar
• Operation with reactive gases including O₂, H₂
• Gas supply from gas purification system via heated UHV-compatible gas pipes allows ultra-clean conditions

Multipurpose-Chamber

• Conceptualized to dry wet samples after electrochemical treatment (Buffer-Chamber)
