Thermo Scientific Quattro ESEM

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.

Features

Quattro S ESEM is a field emission scanning electron microscope capable of generating and collecting all available information from any type of sample material: it is the most versatile high-resolution low-vacuum FEG SEM with extended low-vacuum capabilities for really challenging samples and dynamic experiments. The Quattro S can freely and simply be switched between three vacuum modes, enabling investigation of conductive, non-conductive and high-vacuum incompatible materials:

– High-vacuum mode (<6*10^-4 Pa) for imaging and microanalysis of conductive and/or conventionally prepared specimens;

– Low-vacuum mode (10 to 130 Pa) for imaging and microanalysis of non-conductive specimens without preparation;

– ESEM mode (10 to 2700 Pa) for high-vacuum incompatible specimens which are impossible to investigate with traditional EM methods. ESEM mode can also perform in-situ experiment by adjusting humidity from 0 to 100%. High humidity typically requires low temperature for SEM imaging, e.g. 1 °C.
