Sample Supports: E-chips
The Triton AX system uses custom-made microelectromechanical systems (MEMS) as sample supports to create the in situ conditions within the TEM. All E-chips are designed, fabricated, and quality checked in-house, which gives Protochips an immense amount of control and oversight to ensure quality, proper functionality, and keep cost minimized.
Protochips has an extensive catalogue of Triton AX E-chips to ensure you can find the configuration that best fits your sample and maximizes imaging resolution, with almost 400 combinations of E-chips possible, including the newly designed flow management and electrochemistry/heating E-chips. These specialized E-chips offer complete control over flow and the removal of bubbles during gas-generating reactions to prevent unwanted interference during measurements.
When it comes to nanoscale electrochemistry, Triton AX E-chips are offered in three different commercially available configurations, with working electrode materials like platinum and glassy carbon, as well as the option to use a standard reference electrode such as silver/silver chloride. The goal is to provide an environment that best replicates that of bulk-scale measurements to ensure the nanoscale measurements made with Triton AX can accurately complement bulk scale experiments for a complete story.
For temperature-dependent experiments, the patented embedded heater provides enough power to heat the entire cell of liquid, even while flowing, to ensure a constant, uniform temperature throughout the viewing area for accurate temperature-dynamic associations.
Triton AX E-chips are offered in configurations that enable STEM imaging and EDS analysis even in a liquid-filled cell, where the sample is placed so the STEM probe hits the sample first, mitigating broadening, and maximizing line of site to all EDS detector configurations.

Machine Vision Software: AXON
AXON Synchronicity and AXON Studio are the foundational software modules for Triton AX. AXON Synchronicity machine vision software allows you to focus on on the sample and not the TEM controls, automatically correcting for drift, assisting with focus changes, and aligning all in situ parameters with corresponding images in an indexed fashion for filtering and plotting later. Use AXON Studio to visualize this data in a way that helps identify trends in data that are otherwise not easily seen.
