Description
Features and Benefits:
- VCR seals provide higher levels of system cleanliness, low outgas rates, and base pressures. The result is accurate low pressure chemisorption isotherms and the ability to measure oxygen-sensitive materials
- Standard high-precision mass flow controller provides extremely accurate, programmable gas control
- High-temperature furnace (up to 1100 °C) provides quick and accurate ramp rates to desired temperature with precise temperature control and repeatability (±1 °C)
- A total of twelve gas inlets allow multiple probe gases to be investigated maximizing efficiency and range of applications
- Superior temperature control maintains accuracy and repeatability in monotonic isotherms
- Design permits transition from chemisorption to micropore physisorption within seconds
- New high-temperature, precision quartz cell improves accuracy and sensitivity for challenging analyses
- Heated vapor can also be used as the adsorptive for chemical adsorption analyses
- Kalrez, Viton, or Buna 0-rings provide maximum flexibility for chemical compatibility
Superior Hardware Versatility
- A twelve-inlet gas manifold and vapor dosing are standard with the chemisorption capability. Flow control during sample activation utilizes a mass flow controller (MFC) for precise and repeatable sample preparation. The MFC is included in the standard chemisorption hardware.
Sample Analysis Options
- Gas selection
- Free space measured at both ambient and analysis temperature
- Dosing options added to the pressure table give you the ability to change the pressure increment, volume dose increment, and equilibrium interval time between data points
- Dosing from gas inlets or vapor source
- Repeat isotherm to analyze reversible sorption
Reported Data Includes
