In situ TEM Product Options

Selecting the right in situ system will greatly increase the experimental possibilities of your TEM experiments. DENSsolutions complete lineup of in situ TEM solutions provides precise, accurate, and reproducible stimuli without compromising microscope performance. 

Liquid + Heating or Biasing: Stream is the number one platform for liquid phase experiments. Its patented Nano-Cell enables precise control of liquid flow and thickness while heating or biasing the sample.

Gas + Heating: Climate transforms the TEM into a Nano-Reactor capable of in situ and operando experiments. Continuously mix up to 3 gasses and water vapor at pressures up to 2 bar.

Heating: Wildfire enables dynamic thermal studies by providing stable and homogenous temperatures up to 1300°C with rapid heating and cooling rates.

Biasing + Heating: Lightning builds upon Wildfire’s capabilities by enabling electric fields up to 300 kV/cm at 900°C plus the ability to measure I-V response with pA current sensitivity.

All-inclusive Software

Impulse Software

Impulse software gives researchers complete control over stimuli applied within DENSsolutions in situ TEM systems. With Impulse, you can easily design your in situ experiment from your desk and store experiments so you can reliably reproduce results. While on the microscope, Impulse will automatically control the sample environment while you focus on the sample.

What is In Situ TEM ?

The limitations of conventional TEM

Conventional TEMs primarily act as an imaging tool to characterize structures of materials.

In the last few years, state-of-the-art TEMs have enabled atomic resolution imaging and analysis, which has been achieved through the use of image or probe aberration-corrected TEMs. The performance of these TEMs as an imaging tool has proven to be extremely valuable in identifying various material structures.

However, these conventional TEMs are still unable to support the whole research process. The reason is that conventional TEM is unable to replicate real-world environmental conditions (heating, gas, liquid, etc.) as the sample is always introduced into a static, high vacuum environment.

This fundamentally limits the value and obtainable benefits of a TEM.

The power of in situ TEM

Observing processes “on site” as they are occurring and under changing external stimuli is the paramount goal of in situ, time resolved techniques.

DENSsolutions utilizes MEMS devices, called Nano-Chips, to control the sample’s environmental surroundings and replicate real-life application conditions inside your TEM. The introduction of in situ capabilities into a TEM transforms the system from a static imaging tool into a multi-functional laboratory.

With these in situ microscopy solutions, researchers are now able to characterize structures, measure properties, evaluate performance, and optimize processes & synthesis – all in one system!
