Thermo Scientific Axia ChemiSEM
Thermo Scientific

The Axia ChemiSEM is designed to make SEM more accessible and easier to use, with convenient automated features and live EDS elemental mapping.

Unlike traditional SEMs, it collects EDS data continuously in the background. Unique algorithms process SEM and EDS signals simultaneously, so you can view the morphology and quantitative elemental composition of a sample together, in real time.


Continuous EDS

For quantitative elemental information at any time

Automated features

Designed to make SEM easier to use

Acquire data twice as fast

Compared to alternative SEM-EDS systems

Samples up to 10kg

Large, flexible chamber


  • Live quantitative elemental mapping – Always-on EDS means you can view elemental information at any time without switching techniques.
  • Easy to get started – The platform is always ready to image. Helpful guidance, auto-alignment and automated features enable you to focus on your data, not on operating the instrument.
  • Large, flexible chamber – For samples up 10kg, with x-y movement, and fully opening door for awkward samples.
  • Excellent imaging performance – For a wide range of applications, including insulating samples with Low Vac operation and advanced beam scanning for high-fidelity imaging.
  • Software for diverse applications – Handle advanced applications with system automation options such as Thermo Scientific Maps, and customise workflow development with AutoScript.
  • Easy maintenance – Source exchange can be completed easily by users of any experience level. Straightforward design gives you high up-time, with rapid service when attention is needed.

How to Choose a SEM

A recorded webinar from Thermo Scientific about how to match the features and specification of a SEM to the requirements of your application.

  • How different samples and applications require different resolution performance.
  • What performance you can expect from a tungsten / FEG / in-lens FEG / UC FEG.
  • Dealing with different types of samples: insulators, nanomaterials, sensitive materials, etc.
  • Characterising samples in their natural state without the need for sample preparation.
  • What type of information the SEM can provide.
  • Software features to boost productivity and ease-of-use.
