Gas Supply Systems
On-site control of real-world catalyst reaction conditions.
The Climate Gas Supply Systems are a game changing system for catalyst research. They integrate all control functions into one smooth platform. Optimised for the Nano-Reactor, the Gas Supply Systems control the gas parameters at the sample allowing for imaging and analysis of catalyst particles at the atomic scale. The Gas Supply System Light (included with Climate G) includes one gas line and controls pressure and flow inside the Nanoreactor while the full Gas Supply system (included with Climate G+) adds real time dynamic mixing of up to 3 gases. The user has direct control via the easy-to-use Impulse Software. Reproducible experiments and results can be obtained with a few mouse-clicks!
Ultra Fast Flow Control Unit
Changing gas environment takes seconds, not minutes!
The robust and uniquely characteristic Climate G+ swing arm allows for the Gas Supply System to be positioned conveniently within the lab surrounding the TEM. The Flow Control Unit at the end of the swing arm can be manoeuvred and adjusted based on your lab space, allowing for the Flow Control Unit to be positioned perfectly behind the Climate Sample Holder. As a unique feature for Climate G+, the distance between the pressure controllers inside the Flow Control Unit and the Nano-Reactor at the tip of the Sample Holder is best kept as short as possible to enable fast and direct control over gas flow and pressure around the sample. Typically, changing the gas conditions via the Impulse Software results in the sample environment change in as little as 20 seconds.
Twin Pressure Controllers
Precise pressure control before and after the sample!
As the Gas Supply System for Climate G and G+ has been specifically designed for the Nano-Reactor, twin pressure controllers are mounted in the Flow Control Unit to precisely control the pressure and flow rate before and after the Nano-Reactor (or inlet & outlet to the sample holder). This enables the user to perform experiments with (1) an equal pressure and different flow rates or (2) varying pressures and equal flow rate. Without the outlet pressure controller, a stable back pressure is not possible due to the variables relating to vacuum performance of the pump over time. Therefore, the twin pressure controller setup ensures a reliable flow rate and pressure at the Nano-Reactor.
Patent Protected Mixing Valve
Fast & easy control of the gas composition!
The Gas Supply System for Climate G+ with it’s unique mixing valve provides users with total control of gas composition on-site without the need for a mixing tank. Changing the gases and/or the composition happens within seconds and directly changes the environment inside the Nano-Reactor that surrounds the sample. Similarly to all components of the Gas Supply System, the mixing value is fully controlled via the Impulse Software and allows for customisation of the workflow to the specific needs of the user / experiment.
Mixing Station part of Climate G+
On-site mixing of up to three gases
Three 10L gas bottles can be mounted to the left side of the Mixing Station and connected to the Quick Connect gas inlets. Each gas inlet has a mass flow controller that is calibrated for a specific list of gases. Oxidizing and reducing gases are separated by different inlet lines with the third used for inert gases that can purge the Gas Supply System / Nano-Reactor or dilute reaction gases in an accurate and controlled ratio.
Vacuum Test Tube
Safe & Clean storage of the Sample Holder!
As an integrated feature to the Gas Supply System for Climate G and G+, the Vacuum Test Tube is connected with internal turbo pump to safely store the Sample Holder in a contamination free vacuum environment. Additionally to safely storing the Sample Holder, the Vacuum Test Tube doubles as a leak tester following the assembly of the Nano-Reactor. This ensures that any misalignment done during assembly can be quickly identified before inserting into the microscope. Vacuum Test Tube is also included with Climate Air and can be connected to a stand-alone turbo pump (option) with a KF25 flange.
