EXAMPLES using sol for atmosphere ax
DIFFERENTIATE HEAT VS LIGHT REACTIONS
Atmosphere’s E-chip technology provides direct temperature measurements at the sample, allowing researchers to separate thermal effects from true photo-induced chemistry. As light intensity is adjusted, researchers can choose a constant temperature mode or a photothermal mode to best understand how the light is affecting the reaction.
In this example, the software is placed in the photothermal mode, reflecting temperature changes due to changing light intensity. The illumination provides enough localized heating to initiate a reaction that normally requires temperatures of 350–400 °C. As the light intensity increases, the E-chip records a corresponding temperature rise, while the reaction rate accelerates. Once the light is removed, the reaction stops.
QUANTITATE POWER DENSITY ACCURATELY
Ensure quantitative, reproducible illumination with a calibration workflow using the ex situ power characterization station (as seen in the video on the right) and automated software workflows. An integrated sensor measures the light through its optical path, including through the holder and SiN window, generating a calibration file that reflects the power density the sample experiences in situ.
By enabling proper measurements through the holder, researchers can apply accurately quantified light intensities across experiments, improving reproducibility, enabling direct comparison between datasets, and increasing confidence in photochemical and photocatalytic results.
DIRECTLY INPUT DESIRED PARAMETERS
The calibration workflow allows researchers to simply input a target power density into the software, and the system automatically adjusts laser output to deliver the requested intensity at the sample. This eliminates manual calculations and ensures quantitative, reproducible illumination.
AXON Synchronicity compensates for thermal drift induced by by changing light intensity and AXON Studio provides centralized data management, indexing measurements and images for rapid filtering, review, and analysis. Data can be reviewed directly at the TEM during an experiment, enabling immediate feedback and allowing researchers to optimize experimental conditions in real time.

SAMPLE SUPPORT: SOL E-CHIPS
Sol for Atmosphere AX offers specialized E-chips for both in situ photo-illumination experiments and ex situ power density characterization. Sol E-chips have been optimized to ensure maximum power density at the sample location, providing flexibility to study many different types of light-sensitive reactions.
Sol experiment E-chips are used for in situ TEM studies and feature dimensions optimized to minimize shadowing at the sample while maintaining the environmental capabilities of the Atmosphere platform.
Sol calibration E-chips are dedicated to the ex situ power density characterization workflow and consist of a window-only E-chip paired with a membrane-free, aluminum-coated aperture E-chip. When used with the holder in the ex situ power characterization station, these calibration components account for optical losses through the silicon nitride window and enable accurate measurement of the power density experienced by the sample.

guide back to Atmosphere AX
The Atmosphere AX solution uses custom-made microelectromechanical systems (MEMS) as sample supports to add temperature within the environmental holder. All MEMS devices (E-chips™) are designed, fabricated, and quality checked in-house, which gives Protochips an immense amount of control and oversight to ensure quality and proper functionality as well as keep cost minimized.
Uniquely utilizing silicon carbide as a heating membrane instead of the traditional metal coil, Atmosphere E-chips provide superior uniformity and accuracy to other MEMS chips on the market.
