Sample Holder

True modularity, stability and user-friendliness

The Climate Infinity Sample Holder is a crucial component of the Climate Infinity system, responsible for delivering controlled heating and biasing signals to your sample. Importantly, it also channels mixed gases from the Gas Supply System to the sealed Nano-Reactor within the TEM vacuum column. Fabricated with the highest precision and top-quality materials, it fits your microscope goniometer perfectly and ensures optimal mechanical stability. Moreover, its modular design allows for easy cleaning and replacement of each vacuum component, ensuring contamination-free experiments and future-proof upgradability.

Improved tilt

Better structure characterization

A few improvements have been included in our new-generation environmental Climate Infinity holder. Particularly, the tip of the holder has been redesigned to expand the alpha tilt range of the sample. This provides greater flexibility in orienting the sample towards particular crystallographic planes or directions and maximizes the X-ray collection efficiency. This reduces the time needed for EDS scans for side-entry detectors. The increased X-ray collection angle of the new tip and the ability to flip the tip together further enhance the EDS performance.

Modular & universal design

Clean, complementary & cross-platform experiments

The Climate Infinity Sample Holder’s modular design allows for easy removal of the tip, tubing and manual valves, facilitating on-site cleaning or component replacement. This helps to maintain a clean and contamination-free environment – critical for reliable experimental results. The holder tip has a universal design that fits both JEOL and Thermo Fisher Scientific (TFS) TEMs, which have different, complementary functionalities. Additionally, the assembled tip, containing a Nano-Reactor and comprising electrical contacts, represents a cartridge with a sample. This cartridge can be used for cross-platform characterization for SEM or beamline setups to collect complementary results.

True flexibility

Easily shift between STEM and TEM mode

The Climate Infinity holder features a new electrical contact method and flexible tubing that can be moved together with the tip. As a result, the new tip can be flipped along the holder axis by 180 degrees, changing the position of the sample from the top (default) to the bottom, while keeping the focus point virtually the same and maintaining electrical contact with the chip. This grants you the freedom to flawlessly switch between STEM or TEM mode while maintaining the microscope’s optimal resolution performance. Importantly, you can switch between both imaging modes within a matter of seconds and without the need to disassemble the tip.

Unique upgradability

Perform gas and liquid experiments with the same holder

The new Climate Infinity holder is a versatile solution for in situ gas and liquid experiments. Compatible with Nano-Chips for both research types, it supports various tubing and O-ring options which can be chosen based on the experiment type. Simply select the appropriate configuration of the chips and connect the required Gas Supply System (GSS) or Liquid Supply System (LSS). As a universal holder, it can be upgraded from a gas to a liquid option, or vice versa. Aside from the dedicated chips and supply system, the upgrade includes a specific holder set with a dedicated tip, tubing, and O-rings to prevent cross-contamination between gas and liquid experiments.

Nano-Reactor

The smallest known chemical reactor

Based on advanced MEMS technology, the Nano-Reactor is a functional sample carrier that enables a controlled and clean reactive environment for imaging chemical reactions at the nano-scale. Integrated into the Nano-Reactor is the 4-contact micro-heater and micro-sensor for locally controlling the temperature environment from RT to 1,000 °C. The Nano-Reactor also contains 4 biasing contacts. Together, the eight electrodes enable combined heating and biasing experiments. Replicating a real-world industrial chemical reactor, the Nano-Reactor enables sub-Angstrom resolution imaging and analysis of gas reactions.

Modular Sample Holder

Removable tip & tubing for clean experiments

A clean environment is essential for in situ microscopy experiments. The modularity of the Climate Infinity Sample Holder allows for all components that come into contact with the reaction gases to be replaced or cleaned on-site by the user. This includes the gas tubing, metal tip & lid, O-rings and consumable Nano-Reactor.

Gas Supply Systems

Precise and fast control of your gas experiments

The Gas Supply System is a game changer for gas-phase TEM research, integrating all gas control functions into one smooth platform. Optimized for gas flow through Nano-Reactor, the Gas Supply System enables the control of pressure and flow and allows for gas mixing with precise control of composition at the sample. Importantly, our Gas Supply System allows for imaging and analysis of samples in gas environments at the atomic scale.

Gas Analyzer

Accurate analysis of reaction products

Designed to seamlessly integrate with the Climate Infinity system, the DENSsolutions Gas Analyzer allows for precise analysis of gases generated during chemical reactions within the Nano-Reactor, even in minute quantities.

Vaporizer

Add water vapor to any gas mixture

The DENSsolutions Vaporizer is designed to offer you unprecedented experimental freedom in your in situ experiments. With the Vaporizer, you can independently add water vapor to any gas mixture right before it enters the holder, allowing you to work with and even humidify 3 different types of gases at once.

 

Impulse Software

Total control of your gas environment

The DENSsolutions Climate Infinity system enables users to control critical parameters such as sample temperature, gas flow, pressure, and composition. Additionally, for gas experiments, it is essential to measure parameters such as calorimetry, reaction products and reactor conditions. Our Impulse software has been specially optimized to fluently integrate these large numbers of parameters, facilitating the automation and reproducibility of complex experimental workflows.
