Quattro ESEM
Environmental scanning electron microscope (ESEM) for the study of materials in their natural state.
The Thermo Scientific Quattro ESEM offers exceptional imaging and analytical performance, featuring a unique Environmental Scanning Electron Microscopy (ESEM) mode that allows the observation of samples in their natural state. This makes it suitable for a broad range of academic, industrial, and government laboratories that require flexibility and ease of use for multiple users across different disciplines and expertise levels. The platform is also ideal for conducting specialized in situ experiments. Equipped with a Field Emission Gun (FEG), the Quattro ESEM delivers high-resolution imaging, while its three vacuum modes (high vacuum, low vacuum, and ESEM) provide the versatility needed to handle a wide variety of samples, including those that are prone to outgassing or are not vacuum-compatible.
The Quattro ESEM stands out for its in situ imaging capabilities, making it an excellent choice for dynamic experiments with robust analytical functions. Its ESEM functionality enables scientists to examine materials under diverse environmental conditions, such as wet, humid, hot, or reactive environments, which is particularly valuable in the development of new materials and products. The system supports both cooling and heating experiments in high and low vacuum, catering to a wide range of research needs. For cooling wet samples, researchers can use the Peltier stage, or Thermo Scientific WetSTEM Technology when transmission mode is required. The system also offers several options for heating bulk samples and powders, allowing dynamic high-temperature experiments in high vacuum (using the high-vacuum heating stage), in low-vacuum/ESEM modes (with two heating stages supporting temperatures up to 1,000°C and 1,400°C), and in localized areas (via the Thermo Scientific µHeater Holder), ensuring precise temperature control.
With its spacious chamber, the Quattro ESEM can accommodate numerous accessories. Analytical tools include energy dispersive X-ray spectroscopy (EDS) with dual 180-degree EDS ports, coplanar electron backscatter diffraction (EBSD), and wavelength dispersive X-ray spectroscopy (WDS). Additionally, the system is integrated with the latest Thermo Scientific ChemiSEM Technology, offering real-time elemental imaging through an intuitive SEM interface, ensuring that compositional data is always available
Features
Dynamic in situ experiments
In situ study of materials in their natural state: unique high-resolution FEG-SEM with environmental mode (ESEM). In situ analysis at temperatures ranging from -165°C to 1,400°C with a range of cryo, Peltier, and heating stages.
Wide range of information
Observe all information from all samples with simultaneous SE and BSE imaging in every mode of operation. Several additional detectors, such as the STEM3+ detector and the retractable RGB cathodoluminescence (CL) detector are available to accommodate every user’s need and provide a complete set of information from a wide range of materials.
Excellent analytical capabilities
Excellent analytical capabilities with a flexible chamber that allows multiple EDS, EBSD, or WDS detectors. Elemental information at your fingertips with ChemiSEM Technology, which provides live, quantitative, elemental mapping for unprecedented time to result and ease of use. Excellent analysis of non-conductive samples: accurate EDS and EBSD are enabled in low vacuum with the Quattro ESEM’s through-the-lens pumping.
Minimize sample preparation time with the unique combination of high-vacuum, low-vacuum, and environmental modes
Ease of use with innovative options and advanced automation
Easy to use, intuitive software with User Guidance. The unique Undo function permits efficient exploration of imaging conditions and allows you to work faster with fewer mouse clicks.
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.
