Protochips releases Poseidon in-situ liquid solution for TEM

(July 30, 2010) — Protochips announced the Poseidon solution for in situ characterization of materials in liquid directly within the transmission electron microscope (TEM). Poseidon allows scientists and engineers to image both materials and biological samples that are self-contained within a fully hydrated environment, effectively creating the native environment of a sample directly within the TEM. Samples and processes that previously required freezing or were unable to be imaged live or in their operating environment can now be studied directly in their native liquid environment while observing in real time.

Using the Protochips E-Chip consumable technology for sample supports, Poseidon is an in situ solution that allows scientists and engineers high performance and flexibility for liquid in-situ electron microscopy. By choosing from the Poseidon family of E-Chip consumables, users can configure their liquid environment on a per-experiment basis, including volume and flow path, to address the needs of their particular experiment and sample. By allowing users to configure Poseidon though their choice of E-Chips, the highest resolutions in liquid are possible, with nanoscale resolution through several microns of liquid already demonstrated. This makes Poseidon the perfect choice for applications including cells and cellular processes, gels and soft materials, nanoparticle dispersions, batteries, catalysts, mixing and other fully hydrated samples and phenomena. Poseidon is a self-contained TEM holder with external components that does not require any modification to existing TEMs. This makes Poseidon suitable for new and existing electron microscopes.

"Two of the most important features the in situ market has requested are flexibility and ease of use. No two samples are identical, and the Poseidon solution offers an unprecedented set of features, performance and flexibility needed to finally make in-situ liquid microscopy a viable commercial solution," stated David Nackashi, CEO of Protochips Inc.
