Quattro Environmental Scanning Electron Microscope
The Thermo Scientific Quattro ESEM combines all-around performance in imaging and analytics with a unique environmental mode (ESEM) that allows samples to be studied in their natural state. It is ideal for a wide variety of academic, industrial, and government labs that want the versatility and ease of use needed for multiple users of different experience levels and disciplines on a platform that also supports unique in situ experiments. The Quattro ESEM features a field emission gun (FEG), which ensures excellent resolution. Meanwhile, its three vacuum modes (high vacuum, low vacuum, and ESEM) provide the flexibility to accommodate the widest range of samples of any SEM available, including those that are outgassing or otherwise not vacuum-compatible.

Best in class for in situ imaging capabilities, dynamic experiments with excellent analytical capabilities
The Quattro ESEM is a highly flexible platform for in situ dynamic experiments. The Quattro ESEM's environmental SEM capability allows scientists to study materials in a range of conditions, such as wet/humid, hot, or reactive environments, as they develop new materials and products. It supports cooling and heating experiments both in high vacuum and low vacuum to accommodate the widest range of needs. Cooling experiments on wet materials are possible with the Peltier cooling stage or if the transmission mode is needed, with Thermo Scientific WetSTEM Technology. Additionally, the Quattro ESEM provides several different possibilities to heat the samples of interest, both bulk and powders. Users can perform dynamic experiments at high temperatures both in high vacuum (with the high-vacuum heating stage), in low-vacuum/ESEM mode (with the two ESEM heating stages for temperatures up to 1,000°C and 1,400°C), and on a localized area for better control of the temperature change (with the Thermo Scientific µHeater Holder).
Thanks to the Quattro ESEM chamber size, it accommodates a wide range of accessories. Analytical capabilities include energy dispersive X-ray spectroscopy (EDS) with ports for 180-degree dual EDS attachment, electron backscatter diffraction (EBSD) coplanar with EDS, and wavelength dispersive X-ray spectroscopy (WDS). Furthermore, the Quattro ESEM comes with the new Thermo Scientific ChemiSEM Technology, a unique live elemental imaging capability that is fully integrated into the SEM user interface, providing always-available compositional information through the most intuitive interface.

Advanced automation
Advanced automation is provided in different ways, with either Thermo Scientific AutoScript 4 Software or Thermo Scientific Maps Software, depending on the specific application needs.
AutoScript 4 Software offers control of the Quattro ESEM. Take advantage of a Python-based application programming interface (API) to optimize your in situ cooling or heating experiments or record and monitor dynamic parameters such as temperature, stage position, or pressure.
Maps Software automates large-area acquisition on multiple samples with up to four different simultaneous signals. In addition to a clear increase in the system productivity, it offers a multi-scale, multi-layered visualization environment in which 2D and 3D data and imagery can be imported from any source to correlate different modalities.
